/sci/ please help, I have a shit ton of AP Chem work to do really soon. Can someone help me with this shit?

I hated high school
Any Engineering majors on here? Specifically Mechanical. Just transferred and a bit worried that i had it too easy at the junior college. What would you say is the most important material to brush up on from the calculus and physics series? Also i heard differential equations is used a lot. But i dont know. Universities are notorious for bad professors so i want to make sure i truly know my shit.
I'll bump your thread since I just started mechanical engineering at a community college
>statics
i had no idea what was going on besides a general understanding. i think i just got unlucky though because the class average was extremely low and the book didnt explain shit.
>programming
pretty difficult considering i had already taught myself intro to programming level stuff
>diff eq
a bit more challenging than my community college calculus courses but that may have just been the subject material
i dropped out of engineering after that so idk how the rest of the courses would've went.
>>9140744
I second
>>9141398
Have a decent grasp of Matlab programming, Statics and Strength of Materials.
Where I'm at my differential equations professors were total shit. For the class we actually had to use diff eqs for the professor basically had to reteach the class how to do them. Don't get discouraged though because most instances you need diff eqs for you don't need to do super complex ones.
What is our maximum range with the sls rocket with a light cargo ~1000 kg regardless of time how far out of the solar system could we go?

The concept of range doesn't really apply to spacecraft, instead you would use the delta-v of a specific payload.
Do you ever think that the internet is selecting for a different type of "smart" person?
It feels like the type of person who would've been really smart in 1985 would now simply be spread thin by the infinite amount of intellectually stimulating material at his fingertips.
So now, the "smart" people are actually the conscientious and gratification deferring people, moreso than ever.
I know the two traits are correlated, but they are still different.
Yes
With the amount of information available on the internet, the person who is passionate about learning will be infinitely smarter and better placed than the person whose IQ is merely higher.
Many intelligent yet narrow-minded people can not even conceive of the abundance of knowledge available to them
>>9140708
No, what I mean is that the most intellectually curious are going to be overwhelmed by the amount of avenues they can research/learn about.
Those that are less curious will stick to what they have to study (for school or work or w/e) and be more successful.
In the past, the very curious would have just done further research/experimentation in their own field, because new information wasn't so accessible.
>>9140708
i kind of disagree that this is necessarily true. I feel that with the ammount of information available, a passionate person might flit too quickly between the overwhelming ammount of information available to them rather than reading through a book or long paper in a considered way. There are pros and cons to this. I feel like the access to information and entertainment in general has given us all shorter attention spans because theres so much options.

>Unambiguous detection of individual gravitons, though not prohibited by any fundamental law, is impossible with any physically reasonable detector.[18] The reason is the extremely low cross section for the interaction of gravitons with matter. For example, a detector with the mass of Jupiter and 100% efficiency, placed in close orbit around a neutron star, would only be expected to observe one graviton every 10 years, even under the most favorable conditions.
What?
If the graviton really is the carrier of the gravitational force, than any body experiencing gravity must be expressible in terms of that body interacting with gravitons. If the detector is in orbit, then it must be experiencing the neutron star's gravity, therefore it must be interacting with its gravitons, and substantially. In contrast, it barely interacts with neutrinos at all. Yet it only detects one graviton in ten years? Is this saying that a single, discrete graviton carries a tremendous "amount" of graviry?
Eclipse photo mostly unrelated.
>>9140588
Isn't there something similar with neutrinos. Something like a single neutrino could pass through a block of 1 ly long with only 50% chance of intetaction?
>>9140639
a block of *lead* 1 ly long
I though gravity was not a force, but a bending of space-time.
What are gravitons supposed to interact with ?
If hurricane Harvey dumped it's water on San Antonio instead of Houston
Would it have been less damage?
>>9140537
Alamo's basement would have flooded.
San Antonio here, first of all, we got ripped off, about half or less of the rain than we expected. The big rain stopped just short of us.
The main problem with Houston is that it is FLAT. It is at low elevation, along the coast, with a clay layer a few feet down to help ensure bad drainage. The only bad thing it doesn't have is sub-sea-level areas like New Orleans did. So the drainage is horrible. Areas that aren't flat get filled quickly.
It also has upstream stuff that got rained on. San Antonio doesn't really have any upstream to worry about because of the Hill Country to the north. Rain there drains into the underground aquifer that is the main freshwater source for SA.
https://en.wikipedia.org/wiki/Karst
Back in the '90s there was a storm that stalled over nearby New Braunfels for 24 hours (less than Allison and Harvey), and it was bad, but it was bad mostly along the Guadalupe River. Sure, San Antonio has low spots just like you can expect from any city, but it actually has some sort of drainage. It's also a lot farther from the coast, so a storm can't essentially pipe water in from the gulf like it can to coastal areas like Houston.

G-Guys, check out patent US 20070246939 A1. It just works~
https://www.google.com/patents/US20070246939
having a patent means jack shit. you don't even have to have a working example to get a patent, just an idea.

>I am the only one that knows how to make this Perpetual Motion Motor and it work! I started on it when I was 8 years old, My Father told me that we are the Caretakers of the Earth, So I Established My Goals to make this Perpetual Motion Motor at age of 8 years old and this is my claim! The Magnets are put in a timed working order that they will push and pull in away that will be in Perpetual Motion I Have Worked on this all Alone no one helped Me with this I did it all by myself in 31 Years of work I Paul Wanes McDonald the End of this claim.
I think this is satire.
Wait a second, I thought the US patent office banned perpetual motion patents forever ago, is this not the case?
Hello /sci/
One of my oldest friend and also mentor is now in coma for a Cerebral aneurysm (from 5 days).
How many chance there are of surviving?
>>9140477
50%, he either recovers or doesn't.
>>9140508
Do you have a 300 word essay to back that assumption up?
>>9140567
I don't know so much, cause He was 200 km away from here and now he's hospitalized there.
How would you test that empathy was an electromagnetic connection between brains?
Check whether it disappears when one person is in a Faraday cage.

why does that picture scare me?
>>9140474
Well fuck, I was going to post that
So here, have a long nosed hawk fish, since I came all this way.
What time of day was this picture taken?
>>9140464
I'd have to say some time on august 31 2017

Does the language and its sound, grammar etc. influence the mindset, virtues and ideals of its speaker?
https://en.m.wikipedia.org/wiki/Linguistic_relativity
>>9140344
It does. I saw some studies I don't have on hand anymore, but there are lots of examples of concepts that simply exist in one language and not in another. Like how Spanish speakers don't know what love is ;)
>>9140344
Take a look at loanwords, e.g. Schadenfreude

As we all know all the great mathematicians think very abstractly, stick to general notions and don't use any examples. Does that mean Conway is a brainlet?
>>9140294
for me, yes
>>9140294
>great mathematicians think very abstractly, stick to general notions and don't use any examples
Grothendieck was a very abstract thinker but still had a filing cabinet filled with specific examples

So my house was hit by lightning yesterday, the room in which my TV is located could not turn on any longer, untill the powercord had been removed and reinserted the remote control also stopped working after it had powered on the TV.
My question is one of the batteries (alkaline) in the remote control has burst, is this due to lightning hitting the building and should I be worried for my other devices that have batteries in them?
>my house was hit by lightning yesterday
You've got to be the unluckiest cunt of the decade. How loud was it?
>>9140296
cannot really describe the sound other than it stuns you, like you see the flash and then I usually count how many seconds after the boom hits but it was there instantly. I was also hit by a jolt of lightning that came between my keyboard and hand.
>>9140306
if there was enough voltage to shock you while you were sitting at your keyboard then your electronic devices were probably damaged as well.
I read a story some years ago about a library which wasn't struck directly by lightning, but it was close enough that the EMP induced current in nearby devices and damaged their circuitry. Lights flickered. Several hard drives failed. One unfortunate chap's laptop shut off and never turned on again. Considering your computer still works I would consider you lucky.
Does anyone else find it sad that we are constantly raided by science denial because these people are so afraid of the truth?
Every single day there is a thread about race or climate change denial. Every thread is the same. "It's a liberal conspiracy." Despite how much has been argued on both topics, the threads never stop and they never learn.
They claim science is on their side, but when they cite a picture or a paper they don't understand it. When you point out the paper doesn't claim what they thought it did, they claim the authors were also part of the conspiracy.
What leads these people to be so mentally ill that they think raiding this board will accomplish anything?
>>9140253
If you care about human genetics so much, why not actually get a college degree and educate yourself on it?
>>9140242
We don't need threads like this. It just stirs them up. Just look at the 1st reply...
