Learn About Humanity’s Journey Out Of Africa And Into The Wider World In The “Great Human Odyssey” (Trailer)

Humanity started in Africa. We’re on the same page with that, right. Science!

But let’s go deeper in depth with NOVA’s and PBS’ help. How did ancient humans make their ways to all corners of the Earth; not only surviving Africa but leaving it and coming to thrive as distant disparate populations in the various regions in which they finally settled? HUGE question. And there are more that will be addressed in the “Great Human Odyssey” documentary (available on PBS, and now on Netflix).

Mars: To Boldly Go Where No Human Has Gone Before, Space X Will Need To Get A Lander Up And The Cost Of Relocating To Mars Down (Video)

Wow, so SpaceX is launching its manned Mars lander in 2020? Wow. The goal of ‘making humans a multi-planetary species’ seems kind of far out, and that is the point. Mars is the next planet over, sure, but it ain’t just “next door.” It is far out there.

SpaceX Founder, CEO, and Lead Designer Elon Musk will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. The technical presentation will focus on potential architectures for sustaining humans on the Red Planet that industry, government and the scientific community can collaborate on in the years ahead.
– SpaceX

Interesting. Musk is the first big wig in space matters to address why we are trying to just go back to the moon… It is not a good candidate for terraforming (e.g. we cannot make an Earth-like planet of it). Watch the presentation above and read a bit more below.

Science: LIGO Can Observe The Gravitational Waves Einstein Predicted Over 100 Years Ago (Video)

So, the genius of Einstein is on display once again. But for this bit of knowledge he posited over a century ago, he thought there could never be any real ‘evidence’ to confirm it. Black holes, the collision of black holes, resulting gravitational waves… all fodder for sci-fi books at best in the time of Einstein. Buuuuut…

When Albert Einstein predicted that two colliding black holes could cause gravitational waves in the fabric of space, he was sure to mention he never thought we’d confirm the elusive waves exist. But he was wrong: we did, in 1974, and now scientists are using a giant laser-based experiment called LIGO to try and observe gravitational waves.

Science: When It Comes To A Supernova, How Close Is Too Close For Earth? (Video)

Keep calm and realize that stars going supernova happens all the time across the vast universe. It will eventually happen in or near our solar system. But just how close would a supernova would have to be to wipe out life on Earth? Welp, about 50 light years… about 27 times the size of the solar system… away. Soooo, actually not close at all. In fact, 50 light years or nearer and we are totally annihlated. But we can still be galactically eff’d if the supernova is a further out.

Watch. Learn. Breathe.

How To Find Water In The Desert (Video)

Fact about me: I like watching survival shows; though I am in no way claiming expertise at anything I watch. However, I am tucking this bit of ‘expertise’ in the back pocket of my mind… in the VERY unlikely event I find myself stranded in a desert, cut off, without water.

If you ever find yourself lost in the desert, knowing how to quickly find water is going to be key to for your survival. Here’s what you’re going to need to know.

Food/Science: That’s Not Blood Leaking From Your Steak (Video)

If that KRS-ONE line, “Red and bloody, a corpse neatly packed,” hasn’t stopped you from eating steak, this won’t. Hey, enjoy your steak famlam.

(If it has stopped you, can I have yours? I love a good steak!)

Raw steaks usually have a natural, blood-like liquid in their packaging. Although its red coloring looks a lot like blood, that liquid is not what it seems.
– Tech Insider

Aha! Thought this clip was gonna go ‘anti-artificial’ on you, right? Interesting video. A couple of things: Bloodlike liquid (wtf) and… those percentages don’t add up to 100 (hahaa, thanks to Youtube commenters/fact-checkers for catching that).

Science: Even Einstein’s Blunders Help Explain The Universe’s Wonders (Video)

Even Einstein’s bad ideas end up being pretty darn good.
Brian Greene

Ha! This kind of reminds me of Dr. McCoy’s line in Star Trek IV: The Voyage Home, where he told Spock that Captain Kirk trusted his guesses more than most people’s facts. We can’t even count out the theorems that Albert Einstein tosses out; they might be right.

Brian Greene, Columbia University physicist and co-founder of the World Science Festival, explains how today’s physicists and mathematicians use an Einsteinian formula to explain the universe that Einstein himself originally thought was false.

Science: How Long Could You Survive In Space Without A Spacesuit? (Video)

Okay, I don’t mean it for real for real… but if you actually DO think you could live any significant amount of time in space, kill yourself. This video will show you a spectacular (read: awful) way to do so in the cold vacuum of space.

Why are astronauts always wearing those bulky suits? You don’t NEED them, do you? Here’s what would really happen to an exposed human in the void of space.

Gallium: Liquified Metal That Is Safe To Touch (Video)

I remember everything in my high school chemistry class coming to a screeching halt… because my teacher saw a couple of students break a glass thermometer and ALMOST try to wipe up the spilled fluid with paper towels left on the lab counter.

(I say ‘screeching’ halt because I still remember/hear/feel her SCREECHING yell, admonishing them not to even touch the spill: “Ainh-ainh-AAARRHHH! That is an old thermometer. Mercury. DO NOT TOUCH IT. Back away!”)

Sheezus! That mercury must be a motherf**ker. I got home and looked it up (in my encyclopedias, like Google in book form, old geeks like me remember using them a lot when we were young… Now what was I talking about? Oh yeah, motherf**king mercury).

Mercury is a metal that is liquid at room temperature. Now, there are lots of liquid metals we KNOW to be dangerous to the touch (because molten HOT). But mercury is not gonna burn you for touching it… Check that. I guess you could say injury or death by a metal that POISONS you because it is neurotoxic is a kind of ‘burn’ right?

So, no touching mercury. But Gallium though… You can touch that. You can do all kinds of stuff with it.

You definitely shouldn’t mess around with mercury, but if you want a safe, similar, tactile experience, a metal called Gallium is widely available online. It’s melting point is about 85 degrees, so with just a little heat, you can turn it from a solid, crystal-like state into a fun, reflective pile of goo. Here’s a look at a few of it’s properties and how it’s used in the real world.

Indium: A Metal That You Can Bite (Video)

Random factoid: You know real gold is malleable, right? That’s why you see prospectors, exchangers and ‘testers’ biting down on gold nuggets and trinkets. To see if they can ‘dent’ them. See, you can bite a mark into real gold; most other metals, not so much. On that point: You can bite indium, too. It is much softer than gold though; in fact, the softest metal you can hold in your hand! Watch the clip above. Learn what you can do to and with a bit of indium.

Neil deGrasse Tyson Talks About The ‘Pale Blue Dot’ And Our Place In The Universe (Video)

I remember a show on TV growing up called “Big Blue Marble” that hinted at the smallness of planet Earth compared to the vastness of space; but it still referred to it as the ‘biggest marble’ in the game. But…BUT… watch modern science guy Neil deGrasse Tyson show us just how small our home is as a place in the universe… but still let us know that we are STILL special.

Education: What Is ‘Infinity’… Really? (Video)

I know you are, but what I am I… I know you are, but what am I… Infinity!

If you had a nerdy Peewee’s Playhouse-watching friend (like me) growing up – or if you were that friend – then you instantly got the reference AND significance to the quote above. Hit the jump if you need clueing in. Ahhh, Peewee Herman: debate champ and math scholar. Hahaaaa! Invoking the concept of infinity to shut down a hater. Science!

Infinity is an elusive concept that can often be difficult to comprehend. In order to better define what infinity actually is, we brought in Eugenia Cheng, a mathematician and the author of “Beyond Infinity.”

Hands up if you ever countered someone with ‘infinity plus one’ though. C’monnnnn, you can admit it. That’s the paradox!

(Well, this gives new meaning to Souls Of Mischief’s “93 Til Infinity”…maybe).

Science: A 300-Year-Old River In Canada Vanished In Just 4 days (Video)

Wow. A river dried up about as fast as a big puddle after a heavy rain! Because a glacier retreated too fast. Because climate change (e.g. global warming) some scientists believe.

One of Canada’s rivers has vanished. The Slims River has been flowing through Canada for 300 years, but in 2016 something happened that caused it to vanish in the blink of an eye. In just four days, the river dipped in height so much that it could not recover. Today, the only evidence of the Slims River is its empty, thirsty channel. Scientists attribute the river’s disappearance to our warming climate and predict that future rivers may suffer the same fate.

Politics: Scientists Are Running For Public Office (Video)

Yoooo! When Bill Nye said, ‘Science is political,’ he must have meant for us to take that LITERALLY! Scientists are running for office folks. They are not just sitting by as politicians try to roll back protections for the environment and wage a ‘war on facts’… they are fighting back… with the ballot! Leadership from the scientific community. Cool!

Bill Nye Speaks On His Mission To ‘Save The World’ And On How Political Science Has Become (Video)

The hero we have been waiting for to return… It’s Bill Nye The Science Guy! He’s here to “Save The World” with not only the spread of scientific interest & knowledge, but apparently promoting a point of view. Science is political. You actually know that. Think about great socio-political battles we have fought. They have been over questions that put politics smack dab in the middle of what should be apolitical pursuits: When does life begin (e.g. pro life vs. pro choice)? Are slaves really people or something ‘less than’ that should be owned or controlled (e.g. pre- through post civil war, the battle for civil rights in courtrooms and on congressional floors)? And there is a ‘less uncomfortable’ (but no less important) battle that Bill mentions here… Is Climate Change (e.g. Global Warming) a man-made phenomena that we can/must stop?

As Flavor Flav would say, “We got some nonbelievers out there!” So the fight is on. Save us Science Guy… with KNOWLEDGE… not politics!

The Science Guy sits down with Bridget Carey to talk about his new Netflix show and the three biggest problems the world is facing.

Great interview! Take away two things: (1) Most important, Bill is back, now on Netflix, AND (2) Bridget Carey is hella cute…had to be said.

Science & Technology: Drone Gets Struck By Lightning (Video)

SHOCKING! Hahaa…

Okay, maybe sound the horn on that one (womp waaah). But somebody had to say it. And you gotta see this!

At the University of Manchester’s High Voltage Laboratory, we see what happens when a DJI Phantom 3 drone gets hit with an electrical impulse of 1.4MV – basically, a lightning strike. Actually, two Phantom 3 drones. We had a backup.

This moment brought to you by drones, backup drones, and muthaf**king SCIENCE!!

Science: Just How Deep Is The Ocean? (Video)

I’ve seen videos like this before, and they get me every time. There is a BIG world out there… in the ocean. Sure there is the vast unexplored expanse of outer space, but what about the unexplored areas of our planet. NASA has had some shaving of its programs over time, and it’s unfortunate but understandable. Plus, the opportunities for international partnerships to get some space exploration done could turn out to be better for the planet’s push into the beyond.

But what if we swapped in some oceanic exploration in the U.S. and anywhere else that wanted “in” on the new nearer frontier? There is so much of our planet’s mass that we still know nothing about. Most of it is ocean. We could still spur youths’ daring (remember: kids wanted to grow up to be astronauts back in the day) and societies’ pursuit of bold advances in Science, Technology, Engineering & Mathematics (aka STEM) research. We would definitely find new challenges, cures to problems and diseases, and more. But first, we would have to find courage. Because the ocean is deep. SCARY deep. How deep? Watch!

Just how deep does the ocean go? Way further than you think. This animation puts the actual distance into perspective, showing a vast distance between the waves we see and the mysterious point we call Challenger Deep.

Out Cold: How Long Does It Take To Get Frostbite? (Video)

So wind chill DOES matter. For real! All these years, since bus stop forecasts on the evening news weather reports to just now, I was thinking that wind chill was just a matter of comfort; how long you could ‘chill’ in the wind, so to speak. But naaaaah son, it’s real in the field (AND at the bus stop). It turns out that extreme cold, in concert with wind chill, can freeze uncovered extremities within MINUTES. Introducing… frostbite!

Yeah, I used the word ‘concert’ – but think more ‘lose your fist’ than pumping your fist to ‘Lose Yourself’ if you find yourself in the middle of a windy winter in Detroit without gloves and gear. Just saying.

Frostbite is a serious condition. Cold temperatures can cause the skin and tissue to start freezing, killing the cells. But, wind-chill can drastically change how long you’ll last.
