For everyday use Fahrenheit seems pretty handy. 100 °F is dangerously hot, 0 °F is dangerously cold, you know you have to take extra care if it gets out of that range. And a body temperature of 100 °F is the start of having a fever.

The only number you need to remember is that water freezes at 32 °F. I doubt you'd ever need to know the boiling point of water to cook.

Plus the much smaller increments are nice. °C is good if you're a sciency type and need to convert from Kelvin, but otherwise I don't see many advantages.

America really makes any type of scientific conversion calculation a bitch and a motherfucker.

Also, why not the absolute scale of Kelvin? Why degrees yo?

Heh, I don't think 4.5 thousand million years is normal for anybody to conceive of. I believe the purpose behind saying it that way was to directly compare the magnitude of Kelvin's estimate to the actual estimate we have today. Ie. He estimated 20 million years but the actual age is 45 thousand million years, as in he estimated 20 units but in actuality it was 45,000 units.

If you're referring to my comment. The prequel comics which are supposedly part of the canon is that the Narada is a borg-ified romulan vessel.

They use that as part of the reason why JJverse Enterprise is different from TOS Enterprise. The explanation goes that the Kelvin scanned the Narada and magically gleamed all the borg tech from those scans which led to a massive explosion of new technology. so JJverse tech is supposedly roughly on par with TNG-era tech if not better because of the borg tech boost from the Narada....all that from just scans of the ship.

Don't blame me, that's just what I read

EDIT: just looked it up. Yep, that's what the writers wrote about it.

A science video that uses farenheit.... dear oh dear oh dear. At least one degree celsius and one kelvin are equivalent.

I'm from Canada so sadly even in Farenheit 0 is not approximately the coldest day, we get -40 . My favorite chart for temperature scales though is:

Farenheit: 0 degrees = alive and 100 degrees = alive

Ceslsius: 0 degrees = alive and 100 degrees = death

Kelvin: 0 degrees = death and 100 degrees = death

Back in 1993, I remember this guy with a bad leg, living in a slum in Freetown (Sierra Leone's capital), in a tiny room plastered with Bollywood and Hong Kong B-movie posters, and whose door was made of pieces of cardboard glued together. He didn't have much.
He was called "Prof" Abubakar and made a living creating and selling steel wire sculptures from stuff he was scavenging off the streets. You're probably thinking of African steel wire toys, but his were crazy, there was nothing like it. They were incredibly complex, animated, spring-loaded, or with some sparkling devices.

Some years later, someone I knew came across him. He was exposing at the Pompidou centre in Paris.

Two decades later, it's like Kelvin Doe is his Internet-era spiritual son. I hope he does as well.

Correct name: Abu Bakarr Mansaray (bio | one of his contraptions). He now lives in the Netherlands.

Autoignition temperature
From Wikipedia, the free encyclopedia

The autoignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical will ignite decreases as the pressure increases or oxygen concentration increases. It is usually applied to a combustible fuel mixture.

Autoignition temperatures of liquid chemicals are typically measured using a 500 mL flask placed in a temperature controlled oven in accordance with the procedure described in ASTM E659.[1]

[edit] Autoignition equation

The time t_{ig}\, it takes for a material to reach its autoignition temperature T_{ig}\, when exposed to a heat flux q''\, is given by the following equation

t_{ig} = \left ( \frac{\pi}{4} \right ) \left (k \rho c \right )\left [ \frac{T_{ig}-T_{o}}{q''} \right]^2 [2]

where k = thermal conductivity (W/(m·K)), ρ = density (kg/m³), and c = specific heat capacity (J/(kg·K)) of the material of interest. T_{o}\, is the temperature, in kelvins, the material starts at (or the temperature of the bulk material), and q''\, is the heat flux (W/m²) incident to the material.

To be consistent in units the group \left[ \frac{T_{ig}-T_{o}}{q''} \right] should be squared.

Time is interesting, truly one of humanities and other animals, greatest sensory abilities via memory. In fact how our memory is stored depending on what type of creature you are can give you a wide difference in abilities. Like a fly out maneuvering your swat attempts. Truly time seems not to exist at all if there is no memory. You can also tell that our perception of time was never meant to work with time dilation; this showing that time is extremely relative even just by biological standards.

But, you must remember that if we all died tomorrow and on some distant planet a new species started to learn as we have. They will still have access to the greatest library ever known: The Universe. Does that make time exist? Is it merely just an artifact? Time seems to have an "artificial" standing, as this new species will not see it at "one second" nor will they perceive "one second" the same as us. Time exists, but what is your duration, one tic = the time it takes for the Universe to go from 3k Kelvin to 0 Kelvin, or a few seconds = as we see it?

Much like temperature and other sensory based interpretations of reality. I think it does exist outside our perception, but it could be better stated than is. Perhaps using discreet energy packets in relation to the speed of light interpreted by general relativity for the system, etc... (a much more precise definition of time is using the mechanical nature of particle physics and sharing it with another system, much like nuclear clocks).

This is not a as stupid as you think it is.

Even assuming we could somehow dispose of the extra heat created by such a plan, I'd love to see some calculations on the amount of electricity required to lower the global temperature by 1 Kelvin.


whatever it is, I'm sure it's over 9000
