Sweet Science

High speed video and honey doesn’t usually go together, but this weird quirk of science is worth it.  It goes doubly because he actually explains the math behind the science.  Hopefully you all learn something from this.

1 Trillion Frames per Second

Light is the fastest thing we currently know about.  It travels at 6.7 times 10 to the 8 miles per hour.  That’s fast.  Wicked fast.  Researchers at MIT have come up with a  hardware and software camera that can record at 1 trillion frames per second.  By firing a laser for less than a trillionth of a second, they are able to watch the light travel over time and illuminate objects.

The still life photograph was nice, but I really like the coke bottle one.  One of the interesting side effects of this is because of the hyper speed of the camera, the distance the photons of light have to travel relative to the camera sensor is important.  You see this towards the end with the colorized wave image of the coke bottle.  That’s where the software comes in.  They have to modify the resulting image so that the waves are in the right order chronologically.

Pretty neat.  One of the few TED talks I’ve been able to make it through all the way (partly because it’s only 10 minutes) and understand everything they said in.  You should watch it.

7,000 FPS Lightning

I’ll never get tired of watching storm video.  Especially storm video that’s in super slow motion of 7,000 frames per second.  The above video was captured last week during a storm in Melbourne Florida by Professor Ningyu Liu at the Florida Institute of Technology’s Geospace Physics Laboratory.  The video above is sped up to 700 frames per second, which is still mighty slow.  I really like the instant flash that happens when the timing is just right.  There’s alot of power in these storms, be careful.

Underwater AK-47

It should come as no surprise to you that I am a fan of the Soviet Made AK-47.  Well, actually, maybe it should, considering just how anti-Soviet I actually am, but there’s just no denying a well made machine, and one thing the AK-47 is, is a well made machine, (at least, the original Soviet made versions, the newer Chinese made ones not so much).

The AK-47 is legendary for it’s ability to be subject to the harshest conditions man can dream up, and still fire.  Well, reddit user Onlydead has a high speed video of someone firing an AK-47, while it’s underwater.  There’s not much else to it, but I thought it’s worth the 19 seconds of your time. (60 if you include all the reading you had to do already, sorry).

Impact Crater

Have you ever wondered what happens underground when you drop something.  Or when a meteor, or comet, or missile impacts the surface of the planet (when it even makes it to the planet’s surface that is)?  I mean, the surface of the earth is easy, we have a couple of decades of nuclear blast testing to show that.  But the underground effects, those are alittle harder to see.  Yes, we did do some underground nuclear tests, but those were mostly to just confirm that the bombs worked.

Well, scientists have done experiments to show what goes on.  Using a high speed camera and special polarizing lenses and beads, we can see how the initial impact of a round projectile (more commonly called a ball), dropped effects the surrounding areas.  It’s neat the way the force slowly (or super quickly actually), snakes its way out across the surrounding beads.  The beads work by changing color (behind a polarizing lens) when they are under stress.  So it’s easy to see what’s happening.

Here’s a video showing the above breakdown in a better format:

Firebreathing 2,000 FPS

I might have to agree with them there, everything is better in slow motion.  You get a really nice view of the fire starting.  And in some of them you can see how dangerous the hobby can be, cause you can see the fire start to move backwards towards their mouth.  Pretty cool.
