Using liquid to demonstrate the Pythagorean Theorem
I would love to have one of these to hang on the wall. Maybe a smaller version. In any case it's brilliant. Maybe I'll make a Flash version that uses a simple particle system to show the same thing.
Bill Nye: Creationism Is Just Wrong!
Man know a lot but then we know so little. There is so much to explore and learn. Hubble looked at a black empty in space and found billions of galaxies.
Who is man to be to be the ultimate answer to all things Every decade or so an great discovery comes along and rewrites conventional science thinking.
It takes more faith to believe in creationism that to believe that there is a GOD.
You can not look around at life and simply stake a claim towards to evolution as the ultimate answer.
How does Particle and String theory? Or for that matter what about a Quantum Mechanics ? Really What would the evolutionist have to say about QM? These theories point more to a higher power.
And now it's just a matter of time before either @bobknight33 or the @shinyblurry come in and try to defend creationism.
Oh, did I just accelerate that? Heh heh.... ding ding, round x + 1 bitches... time to get schooled again
MUHAHAHAHAHAHAHAHAHAAHA
Periodic Videos takes a look a the element Neptunium
As a kind of plug (sorry), thorium based reactors are really great sources of Pu238 creation via neptunium exposure to flux. Pu238 is unique among isotopes as to be both physically and radioactively hot, but that radiation relatively benign, weak alpha particles (but your still number one if my heart!). Very simple shielding is needed to keep electronics safe...and a layer of human skin is all the shielding you need for a human . Problem is, isotopes of plutonium are all chemically identical, in a normal uranium reactor, you get the full range of Pu (239 weapons, 240 spontaneous fissions, 241 smoke detector ect). This means you don't get that nice predictable alpha decay, you get a mix of everything...not so good, you need REALLY pure Pu238 to be useful in Radioisotope thermoelectric generator (RTG, the things that powers curiosity). Just one of the many overlooked but awesome things about radionuclides. </end shameless plug>
World War Z - Trailer - Brad Pitt & Zombies
@00Scud00: Spot on observation and finding the right words, thank you! These were not scary zombie masses, these were particles in a CGI fluid simulation. Way too smooth for humanoid bodies to move and behave. Too slick, too efficient. Too clean. Come on. Clean zombies?
Shelving System to Hide your Valuables, Guns & More Guns
>> ^colt45:
So those 82% are all owning guns for murder or war, then? Let's just take this absurd myopic view one step further: Rocks are dangerous weapons that need to be banned! They are readily available to children and highly dangerous!
>> ^L0cky:
Around 6% of US Americans hunt, yet around 34% own a gun; therefore around 82% of gun owners own a gun for something other than hunting. Bringing up hunting is just avoiding the issue.
Besides, I don't think that guy's UZI is for hunting rabbits.
Also, you don't need to teach children how to safely use firearms if they don't have access to firearms. Kinda like how you don't need to teach them how to safely use a particle accelerator, even though they too are dangerous.
Wow. That definitely made my top 10 list of "Really stupid things that I actually read on the internet".
Seriously, when was the last time a kid accidently threw a rock and blew his friends brains out? Accidently put a hole through their own foot / hand / leg?
Sure, they can be used as a close up blunt damage weapon. However, in order to actually kill someone with a rock, it would generally have to be pre-meditated (i.e. kill them when they're asleep, because if you try to kill someone with a rock when they're concious and healthy, it probably wont go well.)
I can think of countless stories over the years involving some idiot irrational gun owner going out and killing someone they knew nothing about, because they felt threatened. Lately, the one I remember is of Trayvon Martin. You know, the kid shot for eating skittles on a street he didn't live on.
But let's go ahead and get back to the point @spoco2 was making earlier. Rocks have existed since the beginning of time. They serve no purpose, they have no design, or goal. They're simply there.
Guns, on the other hand, were designed as an instrument of death. In no part of the gun design was someone thinking "AND it'll function as a paperweight!". It was just another step further in the direction of long ranged combat, specifically for ending the life of another human being.
That's not to say that everybody who does own a gun has it for the sole reason of killing someone, after all, people still collect swords, axes, fascinating weapons from throughout the ages.
But I can't honestly see the amount of collectors being too high.

So you're offering free classes? And you want to live in a country where every child is taught how to use a firearm?
I'd prefer a society where my kids play too much video games, so I tell them enough already go outside and play!
I'd rather that than feel like I live in a society where I have to teach a seven year old how to kill people (sorry, defend oneself with a deadly weapon).
You know, like Liberia or Mozambique.
I don't know enough about firearms, and own none. I'm hardly qualified. Also, please stop putting words in my mouth. I want to live in a civilized country, where people understand PROPER use of, and care for, firearms, including safety, control, and discipline.
Your obsession with murder is a bit concerning. Firearms are very effective at hunting. They are great at providing food from that use. Why you are so obsessed with war and murder, I really don't know. Should you be on a watch list?

"No, there is a different smell and potency to poop. Farts aren't really stray poo particles, although I suppose you could argue them as such. In any case, you should keep in mind that there is no uniform poop particle. Any given piece of poop as a diverse variety of poop particles within it, any one can be different from the other and naturally different from that of a fart." - Serious youtube discussion.
No, mine are more like Cheerios.

Liquid nitrogen + 1500 ping pong balls
I could swear I've seen a hardware-accelerated physics demo on the XBox that did this, but with more particles, I mean ping-pong balls.
Higgs Boson Confirmed!!
Even if it is the Higg's, from my limited understanding, you have to use a linear accelerator to gauge the spin state of a particle (of which it needs 0 spin to be the "Higgs" and a whole number to be a boson).
Higgs Boson Confirmed!!
"Speaking to a packed audience Wednesday morning in Geneva, CERN director general Rolf Heuer confirmed that two separate teams working at the Large Hadron Collider (LHC) are more than 99 percent certain they've discovered the Higgs boson, aka the God particle—or at the least a brand-new particle exactly where they expected the Higgs to be.
The long-sought particle may complete the standard model of physics by explaining why objects in our universe have mass—and in so doing, why galaxies, planets, and even humans have any right to exist."

Higgs Boson Confirmed!!
Ummm.... no.... The Higgs Boson is NOT confirmed by these new papers! It is again, merely proof that they have found a new particle while looking for the Higgs. It is not proven to be the Higgs yet.
