>>7653437 >>7644812 The NOAA/Zeke are using ridiculous TOB adjustments which yield physically impossible results for the more distant past. See pic for an example of actually deleting the data with bad TOB (reset in afternoon); the correct approach to dealing with data errors, you remove them. The rate of warming is miniscule. (Do you seriously think that in 1930, Sally Brown and her other urbanites always reset their thermometer right before the hottest... Comment too long. Click here to view the full text.
>>7653439 >>7644812 Zeke and company rely on general definitions of rural and urban areas instead of looking at the actual conditions (micro-environments) of the temperature stations. The latter is what really counts. If the station is close to an air conditioner belching out hot air, it doesn't matter if the station is supposedly a "rural" station. Accounting for micro-environments is what a "good scientist" would do. See pic.... Comment too long. Click here to view the full text.
Who is the Messi of the math/cs/science world? The one who consistently deliver impressive results that others can hardly pull off and his/her legacy will be remembered the most when he/she is gone? Excuse me for being ignorant, I'm an engineer trying to expand my horizons.
From the top of my head I hear the followings names often, don't know how they rank
Terrence Tao Andrew Wiles Tim Gowers David Eppstein Used to read Scott Aaronson's blog but he went full retard with pc feminist shit and had to put on ignore
>>7653308 No I meant these as fairly seperate questions, Orange was just used a lot in the nineties. The point was if anyone has ideas as to why random things like that would trigger a sort of sadness with no real reason why.
So I'm going through my Biology textbook, we're currently doing animals. This isn't even something I'm supposed to answer, but it bugged me when I read it and didn't understand it.
The question is: "Under which conditions would you expect a bilaterally symmetrical animal not to exhibit cephalization and why?"
Even though it's not something my class is even supposed to do, it's confusing me because I always thought bilateral symmetry gave rise to cephalization. I didn't realize there was any bilaterally symmetrical... Comment too long. Click here to view the full text.
Here is the average amount of trash piling per month in one mid-sized district. multiply this with about 300-500 for the monthly trash of just one city. Now add transportation costs to carry all these to the nearest volcano.
Also, volcanos do not disintegrate trash into the atoms and erase them out of existence. They produce leave a liquid black unburnable residude and toxic fumes by burning plastic and all other synthetic material, which spreads into the air we breathe. Doing this every month is highly pointless and expensive.
you have to believe firmly that most of your profs are not there because they're good teachers, lecturers, educators, people...they generate money and publicity for your school. when i was in uni i would go to class for a week or two and see if i vibed with the prof, then skip class the rest of the quarter and teach myself the material.
>>7653079 This to be honest family, more so when integrating, algebraing the fuck out of functions to fit the formulas is the hard part, mostly because relies on mathematical intuition and algebraic experience more than actual knowledge of what your Calculus book says.
When talking about glueing in topology, are you allowed to stretch your object? If a square is glued like this, it should result in a sphere. Should I picture this square to be glued along its vertices, then "blown" up into a sphere?
>>7653054 It sounds like you have a problem visualising the gluing process. Just see what happens as you pull the sides into the two corners while keeping the boundary connected. I think wikipedia has a gif of the process of making a disk into a sphere, probably on the quotient space page.
How come higher Math is nothing more than alphabet soup? I started off with Elementary Algebra and at least it was understandable when taking notes. I'm now in differential equations and most of the concepts are written like alphabet soup that I don't even understand what's going on. It's only when the professor is doing the homework problems that I understand how to do the steps. I was looking at higher Math and they are using weird ass letters that I don't even know if those are suppose to be numbers or something. Why do we need to decipher what is... Comment too long.

>>7652922 In the set of all possible complete mathematical representations of the universe, there is only one way in which nothing can exist, the empty set. There are however, one assumes, an infinite number of ways things can exist. So, it is infinitely likely things will exist, and infinitely unlikely nothing will exist.
It is a long shot, but someone might can point me to sources.
tldr, grapes, grape juice, wine
is wine superior to grapes and grape juice from a health pov?
Also I'm interested in the health benefits of wine without the drawbacks of alcohol. I know there are alcohol free wines out there, but it is almost impossible to buy them here. So I'm interested in making alcohol free wine by removing alcohol from it. I guess I could achieve this by simply boiling it long enough (e.g. mulled wine), as ethanols boiling point is lower than water, but would... Comment too long. Click here to view the full text.
Hey /sci/, have you ever independently discovered a math theorem or concept?
If so, what did you "discover"?
I realized last night after a Calc 2 lecture in sequences and series that you can use sequences to eliminate all non-prime numbers and consequently find all the prime numbers. Turns out this is called the Sieve of Eratosthenes. I guess I must be at least /greek/ tier.
>>7652828 I guess this was pretty lame, but back when I was in physics 2, I was working through the derivation of the RC time constant, and thought the method used for analyzing the circuit was pretty cool.
So I went to a math instructor and said "Hey, this is pretty cool, given just a relationship between a function and its derivative, you can determine the function! Is there a way to generalize this, it seems really useful."
He told me "Yeah, it's called Differential equations..."
