Do you ever have something randomly pop into your head and you don’t know why? Well I keep having 359 pop into my head so I decided to do some research to find out more about it.
When you mix cornflour with water, it acts like a liquid until you hit it – then it turns into a solid, just for a moment. So solid, that if you fill a bath with it you can jump up and down on it and not sink, but as soon as you stop jumping it turns back into liquid and you sink.
So, my question is, could you use this as a way of creating body armour that would allow you move around but go super-hard when something hit it? Could chemical engineering come up with a way of making a fabric that consisted of loads of tiny pockets of non-newtonian goo that could allow easy movement but would still stop a bullet?
Does this already exist? Would it work as body armour, or would it have to be a bullet proof blanket?
Tell me what you think in a comment!
So, in the vacuum of space there’s nothing, not even air.
Part one of my question is: why don’t the things that do exist in space (eg planets, stars etc) just explode in order to try and fill that vacuum? Is it just gravity that stops this happening?
Part two of my question is about the small scale spaces where there is nothing, ie between the nucleus and the electrons within an atom. If most solid material is actually mostly made of those gaps, how do we (and all solid things) not just implode in order to get rid of that empty space?
If you can answer these, please do so in a comment – thank you!
1. If one correlated particle goes into a black hole or otherwise changes state in a way that only happens with those specific surroundings, and the other one therefore has the same state, would this also change the surroundings of the second particle in order to make sense of that state? So like would it actually make a black hole?
2. I one correlated particle was in another universe very similar to ours, and in one universe they charge the particle, would the other universe’s scientists be able to detect this and would it be a way for us to communicate with them?*
*assuming the many worlds theory is right
If you can answer these questions for me, please leave a comment with your thoughts 🙂
My brain is really squishy but it’s how I do my thinking.
So, how does my squishy brain actually do the thinking? I get how a computer can process things but how does my brain do it? And especially how does my brain enable me to contemplate the fact that I can even contemplate this?
Supplementary question: does my brain work in binary?
Another supplementary question: why is this question so mind-weirding that I almost don’t want to know the answer to it?
Here is my question of the day.
CBBC and CITV are pretty good at having presenters who have disabilities (and not just for programmes that are actually about disability or specifically for disabled people). This is great.
I also saw lots of disabled presenters on TV when the paralympics was on.
But here’s the thing: why aren’t there more disabled TV presenters on regular TV? Why aren’t there lots of newsreaders or weather forecasters with disabilities? Why don’t we see more people with disabilities presenting documentaries (about things other than disability!).
So, that’s my question of the day. Please leave your answers in a comment. Thank you!
OK, so this is what I’ve been thinking about all morning.
Hypothetically, let’s say that there is absolute good, and absolute evil.
If everyone in the world except one person does evil, and just one person does good, the good is still there. But if that one good person dies, and everyone who is left is still evil, would the evil become redefined as good? Or would there still be the idea of good, even with nobody actually doing it?
So, this is my question today. Please leave me a comment to say your opinion.
