I want to start learning calculus(for free time along with starting it for my degree), but I want to make sure I would have a somewhat smooth time understanding it.

I have a hard time understanding the intermolecular forces except hydrogen bonding but the rest is just like...???

Hey guys I'm going to be applying to Uni this year or next year. So I need some books to show that I'm interested for my application. What are the best books you would recommend on Neuroscience? ❤️

Hey guys! I have an Biology, Chemistry, Physics and Maths Exam next week. I have studied for it but they recently told us what is going to be on it. So is there any techniques or study method I could use to cram(?) before my test. I would also like to know what was most effective to u. Thanks!

Could u guys give me science jokes/ pickup lines? I personally really like them but my friend doesn't so I kinda wanna annoy her XD

Hi everyone! The reason I am here now is cause I want to know what computer science really involves? Like what would I do if I were to go to University for the degree? I recently became much more curious in this field cause I want to make sure I won't make a mistake in choosing it. That's all! Thanks!

Do you guys think it would be possible. I personally think humans won't be able to make it possible, but maybe if there is a super advanced race. Be it the whole body travelling through time or the consciousness travelling to another version of the body? This is just a hypothetical question. I also want to know what would you do if you had the power to time travel?

(I think this would be more suitable in the trash can) XD

Free science lessons! They are pretty short too, he simplifies it so well. Though he speaks very monotone to mostly get the point across

How are we doing?

That was an really good explanation. I don't know who u are but u should become a teacher or something(if u aren't already). I feel like I understand Scalers and Vectors a lot more than I did before mostly cause fig 1 and 2.  If u don't mind I'm going to use some of ur explanations in my notes since it was nicely simplified. Once again thank you! ❤️

And opinions and facts don't have 'color'.

I was talking about my skin colour XD

If, in our attempts to make a point, we sometimes say something that you find offensive, simply say so; most of us are considerate enough not to repeat it, and intelligent enough to find an alternate way to make that point.

I'll probably do that instead XD

I didn't mean it in a bad way, just trying to make a point as clear as possible  .

To be clear, if you don't like people of color, for whatever reason, that is perfectly acceptable, and not against the law.
However, you cannot act on that dislike; everyone should be treated equitably, to do otherwise, is against the law.
Sometimes, speech can incite hatred towards certain groups, however, and that is also against the law.

When you start to tell people what, and how, to think, you've gone past the 'slippery slope', and right off the cliff.

Then I've been off the cliff for a long time. I think u kind of of misunderstood what I said I was using POC as an example. And how racism towards that group of people could effect them and how I didn't like that. So I didn't say I dislike people of colour XD I am coloured myself after all.

I meant 'police', the verb, not the noun.

But it's not all about YOU.

Again, if the above offends you, should I be stopped from saying it ?
And by whom ?

What I meant by 'negative stuff' is things that can effect a whole denomination of people. (e.g. racism). And what I mean by racism is the type which is aimed at People of Colour. Just to clarify.

And I am aware it is not all about ME jeez... 

Just now, MigL said:

So who do you think should police and censor what people think ?

Police aren't trustworthy either...I just think they should practice self-control and keep whatever they have to say to themselves. I would rather not hear a person say negative stuff about people.

As a cat owner, I think this mental experiment is an example of ' animal testing' for scientific purposes, and cruelty to animals.

What could be possible ?
Schrodinger's cat is simply an interpretation of the mathematics of Quantum Mechanics, absurdly ( and incorrectly ) applied to macroscopic objects.

Like how the cat has a chance of being dead or alive. It ties in with one of the theories I heard once. 

Say if a cat or whatever dies in a box couldn't there also be another reality where the cat didn't die? Thats what I meant.

I just like whole concept of the thought experiment to be honest

I believe we allowed to say whatever we want. But some people abuse their right of Free speech. (e.g. Abusive language) they then justify it as "Freedom of Speech". So in the end I think people who only say negative stuff about people shouldn't be allowed to always say what they think. Of course there are exception's. Cause Positive and Negative is totally subjective.

One day I was scrolling through youtube and I found a video that was explaining Schrödinger's cat experiment. I personally really like the sound of it and thought "maybe it could be possible?". That was until I went to Instagram and found that everyone was making fun of it...? I was more confused why is it taken as a joke? It is either that the people on Insta are the wrong people to talk to about it, or I am just...the weird one? I hope not. 

You are telling me I can't say I'm a flat universer now? How tragic... T.T

Good for you +1 for encouragement and asking about things.

You will find in Physics that you don't meet everything at once, but learn a little about something and then come back again later to learn some more.

So I will not tell you all about scalars and vectors, just some stuff to hold onto that may help in diferent situations.

Scalars and vectors are part of a heirarchy of types of things (objects) in Physics that are related to coordinate systems.

Are you familiar with the idea of coordinates ?

 

As they are objects they have some special properties.

At the bottom of the list we find scalars.

A scalar has a magnitude or simple numeric value. (Note this could be zero. zero is a perfectly respectable and valid numeric value)
This is the same wherever you are, I see swansont has offered mass as an example.

So a mass of 1 kilogramme is the same in Timbuctoo as Toronto.

Next on the list we have vectors.

These not only have a magnitude but they also have a direction.
The direction is the link that ties into the coordinate system

So we can represent the distance from Toronto to Timbuctoo as a vector.
This will tell us not only how far we have to go (magnitude) but also in what direction we need to set off in order to reach the destination.

 

That is enough to be going on with until you confirm about coordinate.

 

I will mention that the next object in the heirarchy is called a Tensor, in case you hear of them.
A tensor has magnitude and not one but two directions.
But don't worry about them.
 

 

I am familiar with coordinate's but I haven't fully familiarised myself with it though. Your's and mathematic's helped me further understand swansont's explanation. Thank you!

A scalar is something that can be represented by a number (and usually units) Mass, for example. A rock with a mass of 2 kg.

A vector has a direction. It has a value, but also tells which way. Velocity, for example. “moving 10 m/s in the x-direction”

The magnitude of a vector is a scalar 

“I am 100m north of you” represents a vector. “I am 100m away” represents a scalar.

Ur explanation is way better than in my textbook and much more simpler compared to it. Thank you!

Hi everyone! I am currently getting myself started in Physics. But for some reason I can't understand what vectors and scalers actually are.
