DUDE! WHERE'S MY KNOWLEDGE OF SCALE!!

Postby Steppenwolf » Sat Sep 13, 2008 2:13 am UTC

Everyone has done it.

Everyone has winced at it.

Everyone who knows a correct scale will smart, hard, when someone uses it wrong in their field.


So - what is your shame story about getting the "scale" (read - well, I hope you know what I mean here, otherwise, you'll be adding to it soon!) wrong in life?


My prime example:

"We've seen a raise in temperatures before - in fact, a raise of 6oC with CO2 levels hitting 350+ that happened prior to the last ice age, however, this shouldn't dissuade us from making radical changes now, as they're comparable in the last 100 years".

Scale mistake +/- 50 - 75 k years. (Didn't add scale to initial statement) >.<



Add your own.

You know. The kind of thing that leads papers to say "Oh me yarm Oh WE'RE MAKING BLACK HOLES" when sub-atomic particles collide....

My first year astrophysics textbook had a table of values in the front cover, that said the mass of a proton is on the order of 10^-31 kg, which is like saying the USA has 30000 people. I emailed the publishers with their official form, and they told me the next step was to get my professor to confirm. I said fuckem.

Isn't that smaller than the Plank length?

A mass smaller than a length?.....

Was this a brilliant piece of irony?

It is smaller than the Planck mass, but so are lots of things. Most bacteria, for example.
Unless stated otherwise, I do not care whether a statement, by itself, constitutes a persuasive political argument. I care whether it's true.

I had a chemistry problem once which gave some pressure at some given temperature and asked me to calculate what the pressure would be at -5 Kelvin.

I assumed it meant Celsius and continued with that and the teacher marked me wrong :(

Maybe he really did want you to get negative pressure and then say that that's impossible.
Some people tell me I laugh too much. To them I say, "ha ha ha!"

You can actually get negative temperatures.

The odd thing is, its hotter than any positive temperature.

It really does hurt...
This is the last place I expected that to happen to me. It does help that it was also the funniest thing I saw all day.

LMAO. Better get an astrophysics professor to confirm the mass of a proton, because it's not like any idiot with access to the internet could find it in under 10 seconds. That's the kind of thing you should only trust PhDs to answer. :roll:

First thing that crossed my mind was, I thought zero point energy would prevent real negative temperatures.

The second was that the the code was looking for an unsigned int when the temp went negative.
Huh? What?
