Something cool you know.

More people have been to the Moon and back than have sumitted Mt. Everest, Kilimanjaro, McKinley, Elbrus, Puncak Jaya, Aconcagua and both Geographic poles.

Do you mean that there are less people who have summited all of those places personally than have gone to the moon or combined? Cause that's alot of different places.

12 People have been to the Moon.
Fewer than that have been to all those places in their respective lifetime.

I challenge that notion. Top Gear drove to the north pole. Jeremy Clarkson and James May made it in the televised car, but they also had a camera guy, sound guy, polar expert, and a couple of mechanics with them. So unless you're going to tell me less than five people have scaled all those other mountains and been to the south pole then it's bunk.

Clarkson and the people in that exact crew have all made the summits? Or were they separate crews?

You guys know Felicia from Darkstalkers? That isn't actually an elaborate and very revealing outfit she is wearing.

That's her fur. Technically, she is naked.

Ants are the true rulers of this planet and the Human race will fall!
Neat huh?

Random fact of the day:

When in a stressful situation, when the "fight or flight response" has taken effect, humans suffer from relatively extreme forms of erectile dysfunction and constipation.

The pistons in the typical car engine experience shocks in excess of a thousand times gravity every cycle, do this without failure for millions of cycles, all while enduring pressures and temperatures that boggle the mind.


Truly amazing for a chunk of aluminum, eh?

That's nothing compared to the rubber in your tires. Every rotation, a given piece of tread will go from a dead stop (when touching the ground) up to 2x the speed of the vehicle (when at the top of tire) and then back to a dead stop. For an average car (24" tire diameter) traveling at highway speeds (70 mph) this happens every ~0.06 seconds. A typical tire will last somewhere in the neighborhood of 30 million rotations.

...Still has nothing to something that gets ripped about several thousand times a minute with forces equalling several thousand times gravity all while dealing with surface temperatures in excess of 4,000 degrees and pressures well above 1,000PSI.


Tires are noobsauce.

The pressure in gasoline engines on the power stroke averages about 600psi, only diesels reach over 1,000 psi. The temperature of gasoline engines when ignited very very rarely gets over 2,500 degrees, I can't speak for diesel on this point though but diesel does run hotter than gas, still I can't see it reaching 4,000 degrees. Just trying to clear up some points

They went to the north pole, so unless there was some funky wording on your post that went over my head...

i know what you did last summer.

seriously though, eating pineapple makes your vision worse. its the anti-carrot

Thanks to the Leidenfrost effect it is possible (though probably not advisable) to submerse a naked human hand in molten lead.

Thanks Mythbusters!!

The Portal gun must ignore the laws of physics, primarily the law of gravity.
This is because there are gravitational forces between all objects in the universe, especially large bodies in space (ex: stars).
If a Portal is created at position A and another at position B, and both positions are in the same room, the gravitational forces at odds with each other would not be that big of a deal. However, if portal A is in your basement, and portal B is on Mars, it would technically be as if our two planets were touching. The gravitational forces at play would seriously throw one or both planets out of orbit, and/or destroy one planet (probably Mars)

This is why putting a Portal on the Moon is silly.

I understand what you mean, but gravitational fields aren't conserved through portals. If they were, you would get pulled sideways into a blue portal on a wall if the orange one was on the floor, for example. Also, sound isn't transferred through them either. It seems to just be specific forms of matter that get through.

The portal gun operates on the same physics that all games operate on: "This works because we say it does"
While most games have basic gravity, friction and other such things, these rules are only in place because it makes sense to the game mechanics, for it to work.
A game with absolute real physics, wouldn't be fun =/

Technically males and females have the exact same types of tissue and parts, just rearranged differently from the genetic code from the parents sex cells. Things like genitals are just 2 combinations of the same building pieces. For instance the shaft and head of the penis would have formed the labia and the inner parts of the vulva, were it coded for XX or female. Same goes for other physical differences.

The end of a shoelace is called the aglet.

My life has a much brighter feeling now that I know this.

OT: America's first "soft" drink was Vernors Ginger Ale. Got the title "soft" because it didn't contain any alcohol like other elixers at the time.

More than half the cost of building a rocket engine is making a turbopump which can feed the engine bell fast enough to produce thrust.

Does that include the man-hours of engineering, or just the materials and fabrication?

The Engineering.
Being able to pump an Olympic swimming pool of fuel through a pipe about the diameter of a basketball continuously every few seconds that also must be able to keep that pace up for several minutes is a pretty tall order for any sort of technical design. The materials wouldn't surprise me though.

Okay, that makes sense. But keep in mind that pump is being assisted by several times the force of gravity during the thrust phase. I worked on the Delta IV program for a few years, and actually the harder accomplishment was the upper stage engine which had to be able to shut down and coast for hours and then start back up in orbit. All the systems to keep the propellants (LH2 and LOX) conditioned had to work perfectly.

Sun lotion actually becomes mutagenic when it comes in contact with the sun's rays, so it completely defeats the purpose it's supposed to serve. The healtiest thing you should do when you want a tan is not using sun lotion and be under the sun for a short period of time, not hours. It's also better to sunbathe before or after 12 o' clock, because the the sun shines directly upon you.
