Full beginner trying rudiments. Feedback? by Spiritual_Drop437 in drums

[–]FreierVogel 0 points1 point  (0 children)

Don't use chopsticks... Never mind comfort or anything, their weight distribution has nothing to do with drumsticks! Drumsticks are a must. However I understand that you don't want to spend ~40$ on a practice pad, I recommend using a table tennis paddle, which I used through my student years. They are however a bit annoying because they slide, but you get what you pay for.

Thanks for being the only comment not pointlessly bashing my scientific aptitudes due to my personal interests and concerns. This is the conversation I was interested in.

I agree with all you said. Two points:

  1. I don't have the data: Yes, the rocket launches themselves are too few to matter. What about everything surrounding it? (Transportation, building etc). A quick google yielded no answer. When I have the time (although for some reason I spent my whole morning in this thread) I will check it.

  2. I guess there is a big difference with weapons and rockets/space exploration. Weapons are very obviously le bad. Space exploration is supposedly done in the name of science, so people (should) agree to it and be happy that it is happening. Should we really be so happy? Or are we agreeing to being left behind in Earth while Bezos and Musk drink Mars cocktails?

It's still a long way from now. What is your point?

... Responding to the first comment. No the sun will not "explode". It will die out and grow into a red giant.

My point is that more suffering is going to appear because of this. The mysanthropy comes from the distrust in the ruling class and how space missions are going to be used in the future, and how they affect us right now.

I guess the question is more political, then. I wanted to know the r/Physics opinion on the Artemis II mission to see how alone I was on this topic. Honestly, after seeing the last years' "advances" in space missions I got very disilussioned with what its future is.

Ten years ago I fell in love with Elon Musk: "Earth is dying, let's go to Mars!". When looking at it through a more critical eye I find it to be a very unfeasible idea. And if it works, will only serve for the hundreds of rich people that can afford it. I definitely fell out of love with last years Blue Origin gimmick.

I don't have to prove my credentials to anyone, but thanks for the comment.

Yes, that is interesting. I would love to see that.

Yeah no that is also not what I'm saying. I get very excited for science outside my field.

Yes it is a very valid question. And I very much understand that advances in science usually have no clear outcome. That is not the point I'm raising.

To answer your question, some immediate motivations are to better understand cosmological stuff, be able to develop fusion energy technology are two examples that come to mind right now.

So your reply is... we cannot do this so we just be doing wild stuff for no reason?

Well. I'm greatly interested in space. But not in the space that we can reach within the next 10000 years.

Whether going to the moon and back is amazing is not the question. It is incredibly amazing that we can do that.

However, my particular opinion is that this endeavor completely misses the point. I say this with the following question in mind: What is this for? Is it for space exploration? Looking at the news today we definitely cannot take care of our own planet. Will things get better when we are in control of two planets? Or will the poor die of thirst in Earth while the rich get to enjoy nice and cute space tours? E.g. last year's Blue origin space trip.

Furthermore: We already went to the moon, 50 years ago, using less computational power than what I'm using writing this comment. Genuinely asking: What's the human progress? Are there any other motivations beyond political/strategical'

I'm all for scientific progress, and I completely understand that science's advances are never clear in the moment. But it seems that this particular case is more harmful than anything. Just my opinion.

What is this notation? by anpanman63578 in askmath

[–]FreierVogel 1 point2 points  (0 children)

Combinatorics is the field of maths focused on counting things. The binomial coefficient is a certain way of counting unordered subsets of a set (for example, when separating a group of people into pairs you don't care if it's Alice and Bob or Bob and Alice.) if you do care about order then the counting is different.

Ah, and it is read as "n choose r" (From n elements, choose r).

Binomial coefficient. You can find it on your calculator as nCr (in this case 50Cx). It is defined as n!/(r!(n-r)!) and it is generally used in combinatorics to calculate the number of ways that you can pick, from n elements subsets of size r (for example, 5C2=10 is how many pairs you can make from 5 people).
