The rules are simple, decode the code and post a picture of the answer, along with your method.
The code is: 145519121631191914312121

Why does infrared EM radiation feel warm on my skin, but blue or green visible light from an LED, even a strong one, does not feel warm on my skin?

I'm interested in ops question as well..bump

If a bunch of people jump into a pool one by one, they're going to significantly shake up the water. If you get them to all jump in at the same time, you're going to have a decent amount of water ejected from the pool, and then it's no longer shaking. Or if you drop a car into the pool, same thing happens.
There is such a thing as too much energy. With atoms and molecules, the energy that causes jiggling is easier to absorb than the energy that causes significant changes like the ejection of an electron, or the changing of electronic states. What you feel as temperature is caused by the kinetic jiggling of the atoms and molecules you are in contact with. Infrared causes jiggling more so than blue light.

ignore this guy. its flat out wrong.
my sense is its to do with intensity. a toaster/oven uses >300 watts but leds are <10 I think.
might also have something to do with biology but thats not my field. high intensity visible/ultraviolet causes sunburns/cancer but you dont feel it.

I think I finally understand probability.
Everything has a 50/50 chance of happening. Either something happens or it doesn't, 50/50. A dice might roll on a certain number or it won't, 50/50. Literally everything can be deduced to 50/50 probability in life.

Either I will die someday or I will live forever. 50:50
>>
>>7784170
Actually, the chance of you living forever is really small.
You have a 50% chance of living today and a 50% chance of dying. Tomorrow the same so your chance of living are 0.50 to the power of the number of days you plan to live.
If you plan to live infinitely then your chance is infinitesimal.

So apparently matrices work like intended on /sci/ now. [eqn]\begin{bmatrix}1 & 2 & 3 \\ 1 & -4 & 6 \\ 3 & -9 & -3 \end{bmatrix} = \begin{bmatrix} 1 & 0 & 0\\ 2 & -8 & 0 \\ 3 & -15 & -12 \end{bmatrix} \begin{bmatrix}1 & 2 & 3\\0 & 1 & 0\\ 0 & 0 & 1\end{bmatrix}[/eqn] Discuss

Why not make the pizza a different shape in the first place? Ovens are mostly square/rectangle anyway.

Because people want to maximise the pizza to crust ratio.

Is a scientist with an interest in art less intellectual than a pure scientist because the former wastes time with non-science? Assuming both have the same IQ.

no, just because someone doesn't devote all of their time to science and math doesn't mean anything about their intelligence. In fact, studies have shown that people who take an interest in art have a higher-than-average intelligence.
>>
>>7783294
OP stated both are equally intelligence. His question is about intellectualism. Nice reading comprehension, brainlet.
