Just found out about Gorgons and how they ruled their time period they lived in.

What are some other apex predators that ruled the land during their time span? Outside of the obvious Tyrannosaurus pleb of course.

>Lewis and Curry say that their findings show temperature increases will be 30%-45% lower than the climate models say. If they are right, then there's little to worry about, even if we don't drastically reduce CO2 emissions.
You have to remember that there is no projected maximum that the temperature will increase to if we continue doing nothing, there's just projections for time periods.
So a 30-45% lower temperature than projected after 10 years will just mean we reach that temperature in 15-20 years instead.

These reports can be dangerous because they can be used to advocate further procrastination.
Let's just do nothing is not a proper response.

Is it better to pick one science textbook and try to read it through chapter by chapter, or download multiple textbooks and skip back and forth, reading the chapters that interest me the most in that moment?

Hello, and welcome to the 10th SpaceX launch of 2018!
-------
STREAM: https://www.youtube.com/watch?v=I_0GgKfwCSk
Launch Date: Tuesday, May 22 @12:47 PM PDT / 19:47 UTC (instantaneous window)
Launch Site: SLC-4E @ Vandenberg, CA
Launch Vehicle: Falcon 9 Block 4; Flight 2: this core flew on the contentious ZUMA mission!
First Stage Landing?: No
Fairing Recovery?: YES; Mr Steven has left the port and will attempt a 'catch'
Press Kit: http://www.spacex.com/sites/spacex/files/iridium6presskit2018521.pdf
Payload:
>Top Bunk—GRACE-FO; separation at T+00:11:33
GRACE-FO (Gravity Recovery and Climate Experiment Follow-On) is a scientific satellite pair which will detect the local gravity of the earth. It is a follow-on mission to an earlier gravity sensing mission, GRACE, which was active from 2002 to 2017. A large part of the project is supported by DLR, the German aerospace center.
Information: https://gracefo.jpl.nasa.gov
Pre-launch press conference about GRACE-FO (worth the watch): https://www.youtube.com/watch?v=qYJt-6uHVcM
>Bottom Bunk—Five Iridium NEXT communication satellites; separation at T+01:05:48-01:12:28

This is the:

What the hell are you referring to?
The paper you linked says "100%" which isn't "almost" all, it's exactly all. And the one I am was referring to was this. https://arxiv.org/abs/1805.06746 which also states *all* and not almost.

For the anon that was asking whether schools ranked below 20 on US News were worthwhile, I wrote a fucking novel before realizing the thread was archived:

>Are schools ranked #21-30 on US News worth it for math?
Yes lol, US News is infamous for fucking over public schools in its undergrad rankings because of things like endowment per student and student teacher ratio, which disadvantages large public schools. Its formula also uses selectivity, alumni giving, and graduation rates, which screws public schools as they enroll more disadvantaged students.

Berkeley is ranked #21 on US news, behind fucking Rice, Emory, WashU, Notre Dame, Cornell etc, and you'd be retarded to go to any of those over Berkeley for math/engineering. Basically, any of the public schools listed #21-30 are some of the top math schools in the country, particularly Cal, UCLA (#21), UMich (#28), UNC Chapel Hill (#30). NYU, Carneggie Mellon, and perhaps USC are all very good private schools that are worthwhile for math, engineering and other sciences. However, below this the private schools kinda go to shit for math.

Basically crosslist your choices with this list to give you an idea of the strength of the math department: https://www.usnews.com/best-graduate-schools/top-science-schools/mathematics-rankings . Remember that US News fucks public schools for undergrad rankings, but also that a good math grad program doesn't necessarily make for a good undergrad. It does, however, indicate more research opportunities, a higher calibre of faculty, the possibility of taking graduate level classes etc...

I am not a bucket of water. I do not care when I freeze or boil, however I want to know when it's cold enough for the sea to freeze (0F) or when it's uncomfortably hot outside (100F). There's also a higher range of graduation without decimalization. Keep Celsius for science, but it's absolutely garbage for gauging the comfort of people.

2.) What is the probability that no more than 15 like me?

3.) What is the probability that more than 15 like me?

Someone please give me an answer or an equation to figure this out with
