So today I found out something pretty interesting. Branching from the new-found proof of water on Mars, it was actually discovered that a hypothetical element 119 (Was called Ununennium before its discovery) could be found on Mars. Because of the lack of Oxygen on the planet, this element can remain on the planet. It falls under the Alkaline metals category under the periodic table. Like Francium, it reacts very violently to water, except it's speculated that the effects would be 8.6x higher than that of Fr. I can't wait to learn more about this newfound element! (An attachment below shows its place on the periodic table of the elements)
I don't understand.
Does the reaction of Fr and water lead to fission or fusion of Fr into some other element?
Reaction of Li with water gives LiOH and 0.5 equiv of H2 - but doesn't transmute Li into another element.
How do I understand a math textbook? Every time I try to read this Calculus textbook its a huge whatthefuck. I feel really stupid. I'm trying to teach myself Calculus. Anybody know how I can do that? I got an A in Pre-Calc.
You have to
>make sure you understand algebra and trig inside and out
>make sure you have a book that doesn't just suck shit
>It's math. It's only fair that you have to think a bit, isn't it?
My Calc III professor recommends Salas and Hille's Calculus. I'm using Swokowski's Calculus, and it isn't terrible.
This. It's either trig or precalc for your prereq in my state.
Everyone in my first Calc class who took precalc spent the semester in extremely loud agony.
Trig is a very nice opportunity to pick up important knowledge AND important skills. It ties together the entirety of your math education up to that point.
Precalc tells you what a logarithm is.
The guy actually has a good point. Geometry is not Empirical.
That’s what math is— wondering, playing, amusing yourself with your imagination. For one thing, the question of how much of the box the triangle takes up doesn’t even make any sense for real, physical objects. Even the most carefully made physical triangle is still a hopelessly complicated collection of jiggling atoms; it changes its size from one minute to the next. That is, unless you want to talk about some sort of approximate measurements. Well, that’s where the aesthetic comes in. That’s just not simple, and consequently it is an ugly question which depends on...

No shit, retard. None of math is empirical. Science and math are different things and Math is vastly superior because it relies solely on priori truths.
Have fun doing repetitive lab experiments for the rest of existence.
I am sharing draft of Navier-Stokes Existence and Smoothness problem solution:
Any feedback is much appreciated!
This is the logo of my Favorite bar.
Its been bothering me though that I can't figure out what atom it would represent.
Two electron orbits. 2 electrons on one, and 6 on the other.
Can any of you help me figure out what atom this most likely represents?
>six on the other
Enjoy your extra credit in your high school chem class
Do you guys think daily meditation can effect risky sexual/drug abuse behavior? I'm interested in what people have to say.
psychology dept of my college requires survey responses for student research, please help!
I'm not sure if the people that meditate daily are really at risk for drug abuse dude
I do think so. Proper meditation should bring you into a higher state of consciousness, a state of higher alertness. You then no longer try to mentally label things or situations, and sometimes you might feel that things change.
what would happen if Uranus was as close to earth as the moon?
Yes, it's another free will thread.
Do you think we will ever understand "free will"? Will we ever be able to say whether or not it exists?
>A famous pre-Newtonian formula for π is obtained directly from the variational approach to the spectrum of the hydrogen atom in spaces of arbitrary dimensions greater than one, including the physical three dimensions.
Do what do you guys think?
>implying there were rocky planets 1e+10 years ago.
Why do we call it "Base 10"?
Shouldn't it be called "Base 9"?
Hey, /sci/, looking for physics help. I'm not understanding this problem, not looking for homework help per se, just comprehension.
So on a rollercoaster, at the top of a loop (pic related), what is the direction of the centripetal force?
My understanding was that it was always toward the center of rotation. A friend explained that in this case, gravity and normal force (from the tracks pushing back on the car) keep the car in rotation and the centripetal force is negative keeping the riders in the car.
Is this accurate?
Your friend is wrong and probably gay. Centripetal force is always radial and directed to the center. What is keeping the cart moving is the inertia of the tangential velocity at every point.
The plot thickens.
This is my exact problem with the correct answer and in the solution centripetal force is explained to be upward.
How does that make sense?
I have a question about the multiverse theory. How would a species even test for a multiverse? By definition doesn't it mean every universe is completely separate? So here's a multi-part question, feel free to address whichever one you want.
1. How do scientists today test for multiverses? or alternate(higher) dimensions?
2. How would a highly advanced species test for it, like say humanity in 500 years if we advance into space and dont destroy ourselves
I have read before that human legs and the human gait make humans the most efficient land mammals in terms of moving around.
Is this true?
If not, what do you think is?
Also, what do you think is the least efficient land mammal/animal?
An office building has 30 employees and allows 42 square feet of work space per employee. If five more employees are hired, how much less work space will each employee have?
Is there an actual formula for finding Sin, Cos, Tan, etc.?
If not, then how do calculators find it?
