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.
You can have a look at the book here.
This book is really good. One of the good things about it is that you can dip in and out and just read one story at a time. It’s also good because the way the author has used minecraft ideas to illustrate the bible – this would really appeal to someone who likes to use minecraft creatively. There are some really creative ideas, such as:
- To make Goliath a giant, he is nearer the front of the screen
- The plague of gnats was created using fire particles (black dots)
- A beacon was used to represent the ascension, with Jesus rising up into the sky
One of the best aspects of the book is that it’s like a comic or graphic novel – most of the content is pictures, so it’s good for people who would find an actual bible difficult. I really enjoyed reading it, and I learned some bible stories that I didn’t know before. There are captions, and also speech bubbles, to help tell the story, but the pictures are the main thing.
I got this for my 9th birthday, and it was just right, as I’m really into minecraft (mostly pocket edition). It would make a good present to get for your godchild if they are into minecraft, or for a first communion present, or even a confirmation present.
I would totally recommend it.
Why do we go to school?
So we can learn things.
Why do we need to learn things?
So we can go to work and keep the economy going.
Why do we need to do that?
So we can get money to live.
Why do we need to live?
So we can make progress and evolve into something better.
Why do we need to evolve into something better?
Because God wanted us to keep the world going.
Why did the world need us in the first place?
So why did we exist?
But why did we evolve? What was the point of humans evolving?
There is no point.
So what do we do now?……………

…one year later….
Agent One and Agent C ran as fast as they could along the almost deserted road. They could still hear the heavy footsteps behind them, and the click of a weapon being cocked. It was now or never – it was time to test the smart bullet.
Agent One and Agent C both fired simultaneously, over their shoulders without a backward glance – at the very same moment, their pursuer also fired, and the two agents threw themselves to the ground, rolling to be able to see what had happened.
It was spectacular! In the space between them and the gunman, at around head-height, was a silvery cloud of fine powder – and a strange sizzling noise along with it. All three people looked at it in wonder – the gunman looked afraid, but the two agents had smiles on their faces – and turned to high-five each other.
“It worked! First time!” yelled Agent C. It had been her work over the past year that had brought the smart bullet into existence, working on the prototype that she had stolen a year before.
It truly was spectacular – a smart bullet that would instantly seek out any normal bullet that was fired, and disintegrate it using a powerful electromagnetic pulse.
This was something that would save a lot of lives – it had already saved two on this, its test run.
The gunman turned and ran. Agents One and C returned HQ, ready to fight another day.
