Making Solar Panels With A Particle Accelerator

Misconceptions About the Universe - Veritasium

dannym3141 says...

It is simplified.

Some of the concepts are actually pretty hard to put into words and just are how they are. And for each cosmologist you speak to you will encounter a different opinion of the standard cosmological model or parts of its construction.

There are parts of it i don't like because i can't follow and feel comfortable with each step. The maths makes sense, but there's nothing logical and connected in my understanding. At first i didn't like that, but then i realised that we all accept quantum mechanics where charged particles accelerate without radiating, and "instantaneously" move between distinct energy levels.......

In other words, every physical law we've got is just our primitive way of understanding the signals sent from our senses to our brain. Things seem to make sense to us the more experience we have with it happening. We don't understand why matter moves towards other matter via "gravity" - a word which we accept and go 'ahhh gravity - i understand now' but why the hell should it and/or why should it exist in the first place merely to move towards one another?!

So gravity attracts things (why?!) and time only runs in one direction (why!?) and energy is quantized according to the planck constant (WHY!?) and ... the universe is more or less like it's shown in the video! But why why why!? Well, that's a question for a philosopher.

Shelving System to Hide your Valuables, Guns & More Guns

Shepppard says...

>> ^colt45:

So those 82% are all owning guns for murder or war, then? Let's just take this absurd myopic view one step further: Rocks are dangerous weapons that need to be banned! They are readily available to children and highly dangerous!
>> ^L0cky:
Around 6% of US Americans hunt, yet around 34% own a gun; therefore around 82% of gun owners own a gun for something other than hunting. Bringing up hunting is just avoiding the issue.
Besides, I don't think that guy's UZI is for hunting rabbits.
Also, you don't need to teach children how to safely use firearms if they don't have access to firearms. Kinda like how you don't need to teach them how to safely use a particle accelerator, even though they too are dangerous.



Wow. That definitely made my top 10 list of "Really stupid things that I actually read on the internet".

Seriously, when was the last time a kid accidently threw a rock and blew his friends brains out? Accidently put a hole through their own foot / hand / leg?

Sure, they can be used as a close up blunt damage weapon. However, in order to actually kill someone with a rock, it would generally have to be pre-meditated (i.e. kill them when they're asleep, because if you try to kill someone with a rock when they're concious and healthy, it probably wont go well.)

I can think of countless stories over the years involving some idiot irrational gun owner going out and killing someone they knew nothing about, because they felt threatened. Lately, the one I remember is of Trayvon Martin. You know, the kid shot for eating skittles on a street he didn't live on.

But let's go ahead and get back to the point @spoco2 was making earlier. Rocks have existed since the beginning of time. They serve no purpose, they have no design, or goal. They're simply there.

Guns, on the other hand, were designed as an instrument of death. In no part of the gun design was someone thinking "AND it'll function as a paperweight!". It was just another step further in the direction of long ranged combat, specifically for ending the life of another human being.

That's not to say that everybody who does own a gun has it for the sole reason of killing someone, after all, people still collect swords, axes, fascinating weapons from throughout the ages.

But I can't honestly see the amount of collectors being too high.

So you're offering free classes? And you want to live in a country where every child is taught how to use a firearm?
I'd prefer a society where my kids play too much video games, so I tell them enough already go outside and play!
I'd rather that than feel like I live in a society where I have to teach a seven year old how to kill people (sorry, defend oneself with a deadly weapon).
You know, like Liberia or Mozambique.

I don't know enough about firearms, and own none. I'm hardly qualified. Also, please stop putting words in my mouth. I want to live in a civilized country, where people understand PROPER use of, and care for, firearms, including safety, control, and discipline.
Your obsession with murder is a bit concerning. Firearms are very effective at hunting. They are great at providing food from that use. Why you are so obsessed with war and murder, I really don't know. Should you be on a watch list?

ADSR Energy from Thorium

Spacedog79 says...

No doubt ADSR would produce some great science, but it wouldn't address chemistry issues, or any other important issue any better than a LFTR project. It seems to me that it just introduces large amounts of extra complexity and cost. Particle accelerators are big unreliable machines, hence the need for 3 of them for redundancy and they could well reduce safety if something goes wrong. They are not even particularly suited to breeding, as they produce protons which as the name suggests are charged and so need to be very high energy to hit a nucleus and cause fission. The cynic in me says the whole idea was cooked up by the nuclear energy industry to ensure costs could be kept high, and so turn them and their friends in other energy industries a bigger profit (or even just a profit?). My understanding is also that between the various stockpiles of fissile we have, and high breeding ratios from early LFTRs startup fuel should not be a big issue.

I wish you all the best in your learning, I can think of few endeavors more worthy of changing your life's direction >> ^GeeSussFreeK:

>> ^Spacedog79:
The ADSR or "Accelerator Driven Sub-critical Reactor" is unfortunately a massive waste of time. Why not build a properly configured LFTR reactor and it does just the same thing and you don't need to build 3 large particle accelerators to do it.

I agree in one sense, but in another, the chemistry of the LFTR might prove impossible to solve (though this is hardly even a fear atm), so divesting in a "less" effective way to fission isn't a complete waste. Also, you could use this just to breed thorium which would be handy if you hand thousands of thorium generators to start up (you need a good deal of U233 to start the reaction as Thorium is only fertile, not fissionable). This also would be a good way to burn up waste before we get a highly functional LFTR's with the ability to siphon in fission products. In the end, no road should be left uncharted when the end result maybe the salvation of the energy crisis and a life like star trek
I play to dedicate most of my laymen efforts over the next couple of months in learning more about fission for use in determining if I want to drop my life for what is it now and pursue nuclear physics. Pretty sharp turn from where I am now, but I almost feel morally compelled to do so.

2011 Nobel Prize in Physics explained in <2min

Ryjkyj says...

>> ^BoneRemake:
I bet we are in a marble sized universe like in MEN IN BLACK.


Not even that big.

Our universe is simply what you would see if you could see into the nucleus of an atom. It would look just like a swarm of galaxies orbiting around a central point of origin (the nucleus). But it's complex and ever-changing simply because, from the way we see it (from inside the atom), we can't tell that the arrow of time is cycling our universe through representations of every atom that has ever existed.

I think the problem of perception comes from the fact that all the atoms that have ever existed (the ones that the universe represents) were all created from the particle accelerator at CERN. That's why the universe is expanding faster and faster. Because all the atoms that it represents were created in a huge vacuum to begin with.

I don't know why nobody else reaches the obvious conclusion. Or why I always feel the need to explain it.

Orthodox Jews Serenade Sabbath Workers

Smugglarn says...

Hypothesis:

The funny hats and incessant shouting is the result of their devotion to their ancient war god.

The particle accelerator and Nobel prizes are the result of their persecution.

Necessity is the mother of invention

Orthodox Jews Serenade Sabbath Workers

chilaxe says...

Huge numbers of Israel's orthodox Jews get all their expenses (including their high fertility rate) supported by the Israeli state for "religious study," so they not only don't work on Sundays, but not on any day ever.

On the other hand, Israel builds things like particle accelerators and does a disproportionate amount of the world's scientific output, so it's easy to see that they still get a lot done, but they've got a lot of dead-weight to in the form of the parasites in this video.
