Answering the Question "Are We Alone?"

 A TEDx Talk by Shawn Domagal-Goldman

Shawn Domagal-Goldman may be one of the hippest of our current generation of astrobiologists. I've heard him speak several times and have found his manner of speaking profound and enjoyable. Domagal-Goldman's work has focused on global geochemistry of terrestrial worlds, including the Earth, as well as on how we can characterize extrasolar planets from afar to learn more about their surface conditions and possibilities for supporting biology. Here's a video of Domagal-Goldman's talk from TEDxMidAtlantic 2015 where he considers how NASA is currently going about answering the all-important question "Are We Alone?":

"The Greatest Speech Ever Made"

Charlie Chaplin delivering what some people call "The Greatest Speech Ever Made"

If the above image looks familiar to you, then you might be one of the tens of millions of people who've watched the version of Charlie Chaplin's speech from The Great Dictator which was edited by The Lakey Sisters and posted to Youtube in 2011 (that or perhaps you've actually seen the film. In which case, you're awesome!). 

This video was titled "The Greatest Speech Ever Made" and alone has garnered almost 15 million views (many others have since copied and reposted it, driving up the views even higher). 

If you haven't seen the video or haven't even heard this movie speech before, you can check out the link above or watch the video right here:

Definitely an awesome speech. As I mention above, the speech was written and delivered as part of Chaplin's 1940 film, The Great Dictator. This film was produced as a political satire of the war machine and political tyrants, specifically of Nazi Germany and Adolf Hitler. 

Amazingly, the message of the film, and especially of this speech, still hold true today. We are still plagued by fear and jealousy, we still break the backs of the poor and working class to support the aristocracy, we still have the capability to work together to solve our global issues and yet we go our separate ways and we focus solely on our own little problems. 

Our globe is still fraught with people who want to rule others and tell others what to think. People are still "barricaded by hate", and we still see our neighbors withering in pain and hunger while we turn our heads. Yet, as Chaplin said, "the good Earth is rich" and "the way of life could be free and beautiful". We could learn to embrace our technology while still building upon our morality and our understanding of each other and our place in the cosmos. We could progress forward while still protecting the rest of the biosphere. We could live in a world beyond "machine men, with machine minds, and machine hearts".

I don't know if Charlie Chaplin's speech from The Great Dictator is the greatest speech ever made, but it's definitely an incredible testament to Chaplin's capability and thoughtfulness as an actor, a writer, and a human being. 

It's saddening to know that our species is not yet healed of our delusions of power and wealth. To think that we still haven't found a way to unite and surpass our fears of 'otherness' is to realize that we are still, in many ways, children. Chaplin's speech is an inspiration and a remembrance of our need for hope and, even more so, our need to work together to achieve the beautiful future that many of us know is possible.

For those who are interested, here's the script from that speech:

I’m sorry, but I don’t want to be an emperor. That’s not my business. I don’t want to rule or conquer anyone. I should like to help everyone, if possible: Jew, Gentile; black man, white. 

We all want to help one another. Human beings are like that. We want to live by each other’s happiness, not by each other’s misery. We don’t want to hate and despise one another. 

In this world there is room for everyone. And the good earth is rich and can provide for everyone. The way of life can be free and beautiful, but we have lost the way.

Greed has poisoned men’s souls, has barricaded the world with hate, has goose-stepped us into misery and bloodshed. We have developed speed, but we have shut ourselves in. Machinery that gives abundance has left us in want. Our knowledge has made us cynical. Our cleverness, hard and unkind. We think too much and feel too little. More than machinery, we need humanity. More than cleverness we need kindness and gentleness. Without these qualities, life will be violent and all will be lost.

The aeroplane and the radio have brought us closer together. The very nature of these inventions cries out for the goodness in men, cries out for universal brotherhood, for the unity of us all. Even now my voice is reaching millions throughout the world, millions of despairing men, women, and little children, victims of a system that makes men torture and imprison innocent people.

To those who can hear me, I say: do not despair. The misery that is now upon us is but the passing of greed, the bitterness of men who fear the way of human progress. The hate of men will pass, and dictators die, and the power they took from the people will return to the people. And so long as men die, liberty will never perish.

Soldiers! Don’t give yourselves to brutes, men who despise you, enslave you, who regiment your lives, tell you what to do, what to think, and what to feel. Who drill you, diet you, treat you like cattle, use you as cannon fodder. Don’t give yourselves to these unnatural men, machine men with machine minds and machine hearts! You are not machines! You are not cattle! You are men! You have the love of humanity in your hearts! You don’t hate! Only the unloved hate, the unloved and the unnatural. Soldiers! Don’t fight for slavery! Fight for liberty!

In the 17th Chapter of St Luke it is written: “the Kingdom of God is within man”, not one man nor a group of men, but in all men! In you! You, the people have the power, the power to create machines. The power to create happiness! You, the people, have the power to make this life free and beautiful, to make this life a wonderful adventure.

Then in the name of democracy let us use that power, let us all unite. Let us fight for a new world, a decent world that will give men a chance to work, that will give youth a future and old age a security. By the promise of these things, brutes have risen to power. But they lie! They do not fulfill that promise. They never will! 

Dictators free themselves but they enslave the people! Now let us fight to fulfill that promise! Let us fight to free the world, to do away with national barriers, to do away with greed, with hate and intolerance. Let us fight for a world of reason, a world where science and progress will lead to all men’s happiness. Soldiers! In the name of democracy, let us all unite!

Toastmasters: Video Game Voice-Overs and Public Speaking

At a recent Toastmasters Leadership Institute training meeting, I attended a workshop presented by Brooke Chestnut that dealt with the topic of attracting millennials to Toastmasters. 

Millennials, as you may know, are people of the generation who were born roughly between the early 1980s and the early 2000s (a group for which I am technically a member). Our generation has become a powerhouse of creativity and entrepreneurship, although we're also known as a boomerang generation since many of us tend to put off traditional rites of adulthood until later in life. 

Actually, our generation has unfortunately mostly come to be known as a generation of children who feel undeservingly entitled (if you don't believe me, try telling one of the children in America who has gone straight to college after high school that they actually have to read books and do homework to earn good grades and see how they react).

I enjoyed Brooke Chestnut's training session. There were times when it felt a little insulting (I am a millennial after all), but the message was clear: millennials are an important cohort of people who can be benefitted by the improvements in public speaking and leadership that come through Toastmasters membership. During the workshop, we talked about a lot of the thing that are of common interest among those of us in our teens to early thirties. These are things like social media, technology, and video games. 

Video games specifically I thought were an interesting topic to bring up. I've been playing video games my whole life, and I know how important they can be to many in my generation. One thing that I thought about during the workshop was how many great voiceovers have been done for modern video games. These days, video game productions can be massive undertakings and many high-caliber actors and speakers have started taking on voiceover roles. For instance, here's a video with five awesome voiceover parts from some common video games (the video says Top 5, but I don't necessarily agree with that ranking):

The games and voice actors from this video are, in order:

Mass Effect (voiced by George Szilagyi)

Civilization V (voiced by William Morgan Sheppard)

Fallout 3 (voiced by Ron Perlman)

Killzone (voiced by Brian Cox)

Gears of War 2 (voiced by Charles Cioffi)

Due to the nature of video games, many of the great speeches and monologues come before or during some kind of battle. Just as real leaders need to find ways to motivate their "troops" before a serious engagement, it's entertaining to have a great speaker buildup a battle before you enter into it within the digital realm of a video game. To empower the gamer, the voiceover actor needs to use their speaking skills to make the character feel real and dynamic. That's why video games are a growing source of great speaking examples.

Here is a video with Carver's end speech (voiced by Ricardo Chavira) from Dead Space 3:

Here's another voiceover, this time by Jen Taylor at the end of Halo: Reach. It's nice to conclude a game with something more than just the credits:

These video game voiceovers offer some great examples of the power of the speech. With video games continually growing in the scale of their production and their use in society, I imagine that we'll see many more great speeches from video games in the future. For myself, I'll be paying closer attention to the voice overs in the video games that I play, to listen for great writing and great speaking when it pops up. By knowing the ways in which speaking appeals to others, we Toastmasters are better able to share our approach of improvement through practice with a wider audience. I think video game voiceovers may offer some of the great speeches that people will look back on in the near future.

I'll leave you with one more video. Here's a video that someone put together showing Charlie Chaplain's wonderful speech from The Great Dictator set to various video game sequences:

What can the craziest creatures on Earth teach us about the possibilities for alien life?

The flyer for my public talk this week at Fiske Planetarium

Later this evening I'll be giving a public talk at Fiske Planetarium at the University of Colorado Boulder!  I'm thoroughly stoked to give this talk.  We're going to take a journey to some of the worlds in our solar system and also some worlds far beyond and ask ourselves about the types of life that could come to live in such places using the only examples of life that we have to work with, the life from our own world.  During this talk, we will consider some of the craziest creatures on Earth and what they can teach us about the types of alien life that may exist out there.

This talk is part of the Above & Beyond: Cosmic Conversations series, organized by my friend, Morgan Rehnberg (find him at Cosmic Chatter).  These are public talks that are focused at creating conversations between speakers and the audience so that we can all share in the storied wonder of science, human history, and our place in the cosmos.  The Craziest Creatures on Earth will hopefully inspire those of us in the theater at Fiske Planetarium to engage in lasting conversations about how crazy and beautiful life can be, and about whether or not we're alone in this vast universe.  Here's a little overview of what we'll be talking about at Fiske Planetarium this Friday night:

A Multitude of Worlds

An artist's impression of what Kepler 22b might look like

Many of us have dreamed of alien worlds, wondering what planets orbiting other stars may be like.  We've created alien life in our science fiction and we've imagined what a visit to an alien biosphere might be like.  Over the last couple of decades, we have begun to discover only a fraction of the worlds that must exist in our universe.  Yet the only life that we've ever known is life here on our Earth, our home.  As our species continues to explore more of our solar system and to discover other planetary systems far away, it begins to feel like we are continually approaching a time when we might have an answer to the age-old question "Are we alone in the universe?"  What might alien life be like if it exists?  Would it be anything like the life we know here on Earth?

Life on Earth and the
Oddness of the Hummingbird

Life as we know it has been on Earth for at least 3.5 billion years, but probably even much longer.  Through that time, life has evolved to dynamically fit and fill nearly every ecosystem available on the the thin habitable shell and lower atmosphere of the planet.  Since the diversification of multicellular lifeforms during the Avalon and Cambrian Explosions, over 500 millions years ago, plants, animals, and fungi have developed unique body plans and forms of locomotion to better gain energy, fight, reproduce, and live.  

Sometimes an evolutionary adaptation comes along that seems bizarre relative to how we live.  Take for instance the hummingbird.  Hummingbirds are among the smallest birds on the planet, weighing fractions of a pound.  Indeed, the smallest known bird in our modern world is the Bee Hummingbird, which weighs less than a U.S. penny coin.  Hummingbirds get their name from the humming or buzzing sound that their wings make when we listen to them flying.  The hummingbirds's wings beat on average 50 times per second, but have been recorded as high as 200 times per second.  They beat their wings so fast that they can fly up to 34 mph (54 km/h) and they can fly backwards and upside-down.  But that's not the craziest thing about hummingbirds.  

The strangest thing about hummingbirds is that they have a ridiculously high metabolism.  For their little body size, they have a massive caloric intake.  Hummingbird's will eat between 3 and 8 calories each day in nectar.  3 to 8 calories sounds small relative to us, that's really only a couple of grapes worth of energy, but if we consider caloric intake vs. bodyweight, then we can see that hummingbirds eat 77 times more than us.  This is the equivalent of a human eating about 155,000 calories each day.  That's a bizarre caloric intake.  It makes the hummingbird a crazy creature in my book.  

This video discusses research on how hummingbirds maintain their metabolisms

Denny's Beer Barrel Pub in Clearfield, Pennsylvania makes some gigantic cheeseburgers.  One of them, The Belly Buster, weighs just over 20 pounds and holds 25,000 calories worth in energy.  If we had the caloric intake of a hummingbird, then we would need to eat 6 of these calorie-loaded burgers and then, on top of that, we would need to wash it down with 6 800-calorie milkshakes.  And we would need to do this every single day.  That seems bizarre relative to how we understand our place in the world.  

When we consider what crazy creatures like the hummingbird can teach us about the possibilities for alien life, we have to keep in mind that not all organisms function the same way and we may one day find that alien life is wholly bizarre to us.  Maybe there are worlds out there where most organisms have hummingbird-level metabolisms.  Maybe there are worlds where vision or hearing have never evolved.  Perhaps our alien neighbors have forms of locomotion, sensory organs, and even body structures that are adapted to environments with only limited similarities to our world.  To constrain such speculations about alien life, we can take a look at some of the unique environments in our solar system and consider whether Terran organisms could survive in such places.    

Storybots jam vid about the planets of our solar system

Venusian Planets:
A Hunk, a Hunk of Burning Love

Venus is our sister planet.  It's very similar to our Earth in size and overall composition and it even has clouds, but, unlike Earth, Venus is a world completely obscured by clouds.  The thick, clouded atmosphere surrounds and blankets Venus.  That's because Venus has the densest atmosphere of any of the terrestrial planets.  However, if we strip away the cloud layer and take a look at the surface of Venus using radar imaging (from spacecraft as well as Earth-based instruments), we see a chaotic terrain on a geologically young surface.  The surface of Venus is a marred desertscape of volcanoes and plains with ridges appearing as cracks.  From orbital observations as well as from a few spacecraft that landed on the surface, we know that the surface pressure of Venus is 92 times greater than that of Earth at sea level.  Not only that, but the surface temperature of Venus is a sweltering 863 degrees Fahrenheit (735 Kelvin)!

Currently, we know of no life that could survive in the high temperature and high pressure environment on the surface of Venus, yet there are organisms on our planet that have adapted to high temperatures.  Take for instance the microorganisms living along the margins of Grand Prismatic Spring in Yellowstone National Park, Wyoming, U.S.A.

Grand Prismatic Spring: a thermophile's oasis

The center of Grand Prismatic is a beautiful blue of burning hot water, reaching temperatures up to 190 degrees Fahrenheit.  As the water approaches the edges of the spring, it cools to temperatures that can be survivable for certain types of organisms.  The yellows, oranges, and greens at the edges of the pool are pigments within microbes that live in microbial films at the pool's edge.  These organisms are considered extremophiles, as they've come to inhabit an environment that is extreme relative to us.  We know of extremophiles that have come to life in many of the extreme environments of our planet: from places that are hot to places that are cold, places that are acidic or alkaline, and places that are super-salty or even very high in pressure.  Extremophiles have become a target for astrobiologists when it comes to understanding how life may have come to live and to thrive in various environments.  

"The Toughest Microorganism": In the Red

One of the most intriguing worlds in our solar system is our little neighbor, Mars, the 'Red Planet'.  Mars has long held the fascination of scientists and the public.  In the late 1800's, the astronomer Percival Lowell announced he had made observations of striations on Mars that he thought were canals built by an intelligent extraterrestrial species.  Lowell's speculation led to H.G. Wells' story The War of the Worlds and, in many ways, launched the early era of alien science fiction.

Mars has been our most visited neighbor.  We've sent orbiters, landers, and rovers to the Red Planet to learn more about it's geology as well as the possibilities for it to once have had life or to perhaps even currently have life.  Mars has a great volcanic mountain, Olympus Mons, which is almost 3 times taller than Mount Everest.  Mars bears one of the largest canyons in the solar system, Valles Marineris, which is a distinguishing feature when Mars is viewed from far away.  The Martian surface is a cold, dry, and dangerous place for most of life as we know it.  The surface has an average temperature of around -80 degrees Fahrenheit and there's only around 200 parts per million water vapor in the atmosphere (the Earth's atmosphere has an average of about 10,000 parts per million water vapor).  We've known for some time that the surface of Mars is bombarded by intense radiation, since Mars doesn't have the strong magnetic field or the atmosphere that Earth has to protect us from radiation.  However, we've recently learned from the Radiation Assessment Detector (RAD) instrument on the Curiosity Rover that the surface of Mars has even more radiation than we had previously thought.  The first astronauts that we send to Mars will most likely have to employ shielding of various types to protect themselves from the radiation.  

Although the Martian surface will be a dangerous place for humans, there are some organisms on Earth that could easily survive the radiation on Mars' surface.  Take for instance Deinococcus radiodurans.  The Guinness Book of World Records title holder for "the world's toughest microbe", D. radiodurans is an extremophile that can withstand environments with limited nutrients and extreme dryness and, most importantly, can withstand extremely high doses of radiation.  This microbe can withstand a radiation dose over 1,000 times more than what would be lethal to a human.  It can survive in the cooling fluids of nuclear reactors.  The microbe's very name stand for "strange little berry that can withstand radiation" while some people like to call it Conan the Bacterium.  Indeed, D. radiodurans can even survive in the empty vacuum of space.  D. radiodurans would have no problems surviving a trip to Mars and even sitting on the Martian surface.

The extreme radiation resistance of D. radiodurans might even make us wonder about alien life that could survive long-term within the emptiness of space.  Perhaps there are biospheres where life has learned to launch itself out into space, like little spores traveling between worlds.  Perhaps some alien has even adapted to the space environment and become a fully space-fairing creature.  What would such a creature look like?  Perhaps it would be something like the Tin Man from Star Trek: The Next Generation or Moya from Farscape or perhaps something utterly strange.  Would such a creature be anything remotely similar to life as we know it.  Would it need to stay close to stars and planets to maintain itself?  Those are the questions that bridge between science and science fiction.  But we do have good reason to wonder about how organisms get their energy and how biospheres are built.  Much of life as we know it here on Earth is built upon the primary productivity garnered by organisms that utilize the light of the Sun for energy, but not all life on Earth requires sunlight to survive.

Life in Deepest Seas and the Curious Blobfish

My graduate advisor, Alexis Templeton, is the head of a team of researchers centered here at the University of Colorado Boulder and including members from several other institutions which have recently been awarded a grant from the NASA Astrobiology Institute to study what they are calling "Rock-Powered Life".  Their work will focus on understanding how biology on Earth has come to utilize chemical reactions between water and rocks for sustenance.  Life as we know it does not inherently require sunlight to drive primary production.  Rock-powered life may be the base of biospheres on other worlds.  Take for instance the Galilean moon Europa.

Europa (NASA)

Europa is a small moon of Jupiter that might have some big surprises in store for us.  The surface of Europa is a cracked icy shell, maybe 1 to 10 km in thickness, underlain by a deep subsurface ocean.  The ocean of Europa may be as deep as 120 km, making it one of the largest oceans in our solar system.  In fact, all of the water in the ocean of Europa is more voluminous than all of the water in all of the oceans, and rivers, and lakes of Earth!

Comparison on water on Europa vs. Earth (Kevin Hand)

Many of us now wonder if the subsurface ocean of Europa holds a subsurface ocean biosphere.  Perhaps there are hydrothermal vent systems on Europa's seafloor.  Perhaps, much like on Earth, those hydrothermal vent system have become oases of life, where rock-powered life sets the stage for the development of other organisms.  Could there be deep sea marine animals on Europa?  What would they be like.

Here's a crazy creature that might help us answer that question: the Blobfish.  These organisms inhabit deep sea environments off the coasts of Australia, Tasmania, and New Zealand.  Living where the pressure is several dozen times greater than at the surface, the Blobfish has developed a unique way to maintain its buoyancy.  While many fish use gas bladders to control their position in the water column, the Blobfish has body of gelatinous flesh that is slightly less dense than water, allowing the Blobfish to control its buoyancy in deep sea settings.  However, when the Blobfish is removed from its natural setting, the one to which it has adapted so well, and brought to the surface, its body structure changes and it basically slumps into a gelatinous mass.  This has earned the Blobfish the vote as "The World's Ugliest Animal".

The Blobfish can survive the extreme pressure of the deep sea, but it's only adapted for that environment.  When we consider what alien life may be like, we need to be sure we're considering the types of environments where life might have come to be and where life might be best adapted.  For instance, what kind of life, if any, could come to live in the environments of gas giant worlds?

Sagan's Floaters and Hunters...  and Blowfish

In Carl Sagan's television series Cosmos: A Personal Voyage, he discussed speculations about what types of organisms could come to thrive in the vast atmospheres of worlds like Jupiter:

Floaters and Hunters.  What might they look like?  Giant balloon organisms?  Giant floating whales?  In my mind I wonder if maybe such atmosphere-bound life might develop develops defense mechanisms like a blowfish.  Maybe the floaters are giant blowfish-like balloons that can change their position in the atmosphere by bringing in or pushing out gas, and maybe they even look something like blowfish, with spikes and other defense mechanisms adorning their bodies to keep them safe from the Hunters.

As Carl Sagan said, we can constrain our thoughts about the possibilities for extraterrestrial life through physics and chemistry, but these are truly speculations.  Until we have examples of alien life to work with, the best we can do is work to understand life on Earth and try to use what we know of life to understand which environments alien life may have come to call home.  We can look at worlds like Venus, Mars, Europa, and Jupiter and ask these questions.  We can also look further, to other worlds around stars far away.

Exoworlds and the Possibilities of Perception: The Greater Wax Moth and the Mantis Shrimp

Since the discovery of 51 Pegasi b, the first extrasolar world we've found, our conception of the number of alien worlds that exist in our universe has been radically expanded.  As of today, we have found over 1800 exoplanets and that number is always growing!  The worlds we've detected around other stars exist in only a small fraction of the space within our galaxy.  Considering the number of planets we've found thus far, it has been estimated that every star in our galaxy should have, on average, at least one world.  Of course, some may have none and some may have many, but this still leaves a great number of possible worlds and possible environments for the development of extraterrestrial life.  What might those aliens look like?  Astronomer and artist, David Aguilar of Aspen Skies has been using his artwork to propose some ideas.  He creates models of speculative alien life based on his knowledge of life here on Earth and then places those modeled aliens into digitally created worlds.  In what ways can we constrain such work, such speculations?  Perhaps we can consider something like sensory perception.

Take, for instance, the Greater Wax Moth.  This organism has the greatest range of hearing of any known organism on our planet.  Not only that, but the Greater Wax Moth has a hearing range that lies outside of the range of sounds that we humans hear.  It has alien hearing here on Earth.  It's evolved such hearing so that it can hear at frequencies up to 300,000 Hz, allowing it to "out-hear" it's natural predator, the bat.  Bats use high-frequency sounds in their echolocation.  It allows them to "see" what they hear.  The Greater Wax Moth has evolved to hear and to speak above the frequency at which bats echolocate.

An even crazier creature might be the Mantis Shrimp.  The Mantis Shrimp has the greatest perception of light and color of any known organism.  While we humans only have 3 color receptors in our eyes, Mantis Shrimp have 16!  Writing in his webcomic, The Oatmeal, Matthew Inman has said of Mantis Shrimp that their sight is like a "thermonuclear bomb of light and beauty"!  Not only do Mantis Shrimp have the greatest vision of any known organism, but they also happen to pack the hardest punch:

The Mantis Shrimp is a crazy creature.  It sees in ways that we can't comprehend and it kills using a deadly knockout punch.  Might there be alien worlds where the vision of the Mantis Shrimp is only the beginning?  Or worlds where the deadly force of the Mantis Shrimp's punch would be considered puny?

What Beings May Come?

What could organisms like the Greater Wax Moth and the Mantis Shrimp teach us about alien life?  What about the Hummingbird, extremophiles like Deinococcus radiodurans, or the Blobfish?  When there are aliens such as these living amongst us, perhaps it suggests that the possibilities for life in the universe are endless.  

I didn't even start to touch on intelligence and consciousness, robots and machine life, or even some of the myriad ways in which microbes might dominate alien biospheres, and yet there are great examples to be found in those realms as well.  The bridge between science and science fiction lies not only in imagination, but in considering what may yet come to be.

As Carl Sagan mentioned in that video from Cosmos, there is no predictive theory of biology.  Not because it doesn't exist, but because we don't yet have enough to go on to determine if there could be one.  Maybe life does follow certain rules and we will one day find that many aliens are very similar to us, or maybe life follows few rules and alien life will appear utterly and wholly alien to us.  Considering all of the crazy creatures on Earth can help us to constrain our speculations about alien life, but, until we determine if we are or are not alone in the universe, all we can do is continue to look at our one example of a biosphere and say "what might this mean?"

Quotes for Table Topics

I'm a member of See You Speak Toastmasters, a local public speaking group.  If you haven't heard of Toastmaster, you should definitely check it out.  Toastmasters is an international organization focused on building better public speakers, and, through that, our members also become better leaders as well.  Every Toastmasters club is a little different; ours is an informal, small club where we have a lot of fun working on our speaking skills together.  One of my favorite parts of Toastmasters is an impromptu public speaking game that we play called Table Topics.

Table Topics are short speeches that members and guests give during the meeting so that they can work on their off-the-cuff speaking.  I think of this game as the bread-and-butter of the Toastmasters speaking program.  We give longer prepared speeches (usually in the range of 5-12 minutes) that help us to work on our speechcrafting, but Table Topics gives us a chance to practice our speaking skills in the best way: unprepared.  Replying to questions or prompts without having had the time to prepare helps us to become better extemporaneous speakers.

I'm taking on the role of Table Topics Master tonight for one of our meetings.  I've decided to use the theme of "interpreting quotes".  I'm going to pick a few quotes and then have our members and guests interpret what those quotes mean to them.

Here's the list of quotes (from speech and writing) that I'll be selecting from for our Table Topics tonight:

"The key to immortality is first living a life worth remembering."
-Bruce Lee

"All children are artists. The problem is how to remain an artist once he grows up."
-Pablo Picasso

"The greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves."
-Victor Hugo

"I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed."
-Michael Jordan

"Whether you think you can or you think you can’t, you’re right."
-Henry Ford

"All that is gold does not glitter, not all those who wander are lost; the old that is strong does not wither, deep roots are not reached by the frost."
-J.R.R. Tolkien

"Everything you’ve ever wanted is on the other side of fear."
-George Addair

"We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained."
-Marie Curie

"If you want your children to turn out well, spend twice as much time with them, and half as much money."
-Abigail Van Buren

"The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom."
-Isaac Asimov

"It’s not the years in your life that count. It’s the life in your years."
-Abraham Lincoln


We give our members and guests 1-2 minutes to answer the question or prompt for a table topics speech.  What would you say about these quotes in 1-2 minutes?

We follow our round of Table Topics at our meetings with evaluations of how we did during the meeting.  We evaluate the prepared speeches, we evaluate the timing and use of grammar for our speakers, and we have someone called the Quizmaster who's job it is to pay attention during the meeting and then evaluate the club to see if we were all paying attention.  

I highly recommend Toastmasters.  Joining Toastmasters is one of the greatest things I've done for myself in recent years.  It's improved my speaking skills but also helped me to realize that I may have it in myself to become an orator.
