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.

No, this element wasn't created, or anything. Small amounts of it were found on the planet.

How does one "hypothesise" about elements? How do you guess if an element exists?

Does this method find all possible elements or are there some we still might be unaware of?

My Calc III professor recommends Salas and Hille's Calculus. I'm using Swokowski's Calculus, and it isn't terrible.

>>7652072
if you had to take pre-calc i'm sorry but there likely isn't hope for you having a chance at an easy understanding

it's just the truth

>>7652112
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.

also Fluorine.

Enjoy your extra credit in your high school chem class

false. it doesnt represent any atom
fluorine is somewhat the closest but has electron configuration [math]1s^22s^22p^5 [/math]

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.

Do you think binary is "Base 1"?

What I'm not understanding is the direction and role of centripetal force in this case. And what force is pushing upward (keeping the riders from falling out).

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.
https://answers.yahoo.com/question/index?qid=20071125162300AAk4fw9

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 can ejaculate 90 times a day

90/24 = 5.625 ejaculations per hour, assuming 8 hrs of sleep

lolwut? not even don jon fapped that much

>>7650888
Well. The initial thought is consumption of dopamine precursors (L-DOPA, perhaps via mucuna pruriens). Normally after orgasm prolactin levels rise and drive it down. Prolactin is involved in a sensation of sexual satisfaction, elevated levels reduce libido, and problematically, levels that are too low have been shown to result in a reduction of sex drive, So the only viable way to approach it from that angle is some way to only modulate hormonal and neurotransmitter regulatory factors, something that is unknown to me and probably not even readily possible.

The other option is to approach it psychologically. A thing where advice can't really be meaningfully communicated.

>>7650888
How do you have the time to jerk off 5x a day? All after work? Imagine how productive you could be if you didn't waste your time like that.

It is correct. You aren't ignoring reality - the E field and B field transform into each other.
That's why real scientists use shit like tensors and differential forms.

It's just the principle of relativity.

Look at it this way: a magnetic field is set up between two charged particles if they are moving relative to each other. If you make your coordinate system move with a certain particle, then the magnetic field is zero with respect to any other particle that is also fixed with respect to the coordinate system. In other words, the two particles are not moving relative to each other, so the magnetic field between them should be zero. That makes perfect sense.

It makes calculations easier because now you can eliminate all the terms for particles that are fixed relative to your coordinate system. They're just 0.

>>7650714
Yeah I understand that. But from a practical standpoint I can't design my wire system to run through a magnetic field and say, "oh if I just make my coordinate system move then I don't have to account for the magnetic field in this design."

>>7650666
Yes. The sun is actually an elaborate construction of a mirror like material. A number of planets orbit on the inside.

There might also exist a huge number of planets consisting of a material that is both massless and that doesn't affect electromagnetic waves in any way.

Now you know them.

Speaking from personal experience, I use to smoke habitually and became borderline schizophanic at the time. I was never a part of the culture, I just happened to be around people who smoked a lot.

Granted, I was taking frequently vyvanse and getting high at the same time (which I'm certain is an awful, awful combination), I found myself becoming increasingly paranoid and losing touch with reality. At one point in time, I was half convinced I was a messiah at some point along with a tulpa. I was in a weird place...

My roommate, who was providing it to me, would frequently lock himself in his room and smoke several bowls while listening to GREEN AND PURPLE on repeat. Dude was convinced (for reasons I don't understand) that I was secretly plotting to kill him in his sleep.

This all went on for about 9 months. When I decided to quit, I quit cold turkey. No cravings, no lapses. It'd be about 6 months until I smoked again. Mind you, all this happened about 3 years ago, and I've maybe smoked an average of once every 2 months tops since.

Provided that these are all anecdotes, I still don't believe weed is entirely safe. I support legalization, but it really does fuck with your head after long periods of time in inperceptible ways. It wasn't until I quit that I realized exactly how fargone I'd become.

>>7650643
Most things are both good and bad. Some of that can be reduced to relatively objective measures, such as compromised core functionality. Some depends on the individual's psychology or physiology. The rest is up to opinion and personal desire.

Weed is more or less the latter two. I don't like it because it separates me from the stream of my thoughts and is apt to push me into memories I don't want, then ditch me there. It also makes me burnt, stupid, and extremely afterwords. Fuck all that.

I know people who have been daily stoners for the last 40 years. Many of them show no meaningful differences when compared to other likely non-stoner populations. Though that isn't to imply major differences don't exist, it just means their mental faculties, memory, etc are intact.

the dangers of pot, from more harmful to least harmful:

-smoke, its fucking bad for your health. I mean seriously bad

-it can become a bad habit, which reinforces other bad habits. you become lazier, less motivated, your short term memory becomes slightly worse. all this is reversible though (given that you are over 20 yrs old and not fucking up your teenage developing brain) and varies from person to person.

-can trigger psychotic episodes-paranoid behaviour. I put this last, because it happens to a very small percentage of users, and usually they freak out, realize pot is not for them, and never touch it again.
