Honestly the QC threat is very over stated. Don't forget that a 1000bit quantum computer *cannot* help at all for a 1001bit number/system. Also a 1001bit quantum computer is 2x harder to make than a 1000bit one. Also we are miles away from 8bits. Hell even if you get all the bits there are massive problem with the factoring method using a huge number of quantum operation giving further problems for decoherence.
Long story shot. It has not been shown that it is even physically possible to have a quantum computer of sufficient bits in this universe.
True. But current situation seems to be quite beyond the sweet spot. Modern cars could be much simpler and reliable were not for the programmed obsolescency engineered in them.
You really believe that don't you. Then show us how to make this fabled car that lasts 2x longer than what we have.
Current reliability and lifetimes of modern cars is just short of miraculous. Do the math. show me your stress cycle fatigue curves. The wear rates on even the hardest alloys and expected lifetime wear. Modern cars are bloody amazing. And Cheap to boot.
Niven ring is as bad as a solid sphere. It is not stable and serves no practical purpose other than bad scifi stories. If your going to go for big rings out of magic material, the orbitals of the culture universe (Iain Banks) make the most sense.
Yes of course we have done the math on this. Do you really think a bunch of/. think that laterly that half a century of astronomers didn't think of it? On top of that we actually do sit down and run the numbers, rather than suggested lame things repeatedly that are 100 and thousands of orders of magnitude out of the ballpark.
And so are spheres. The original dyson sphere is not a sphere. What was proposed was in fact a swarm. There really is no reason to do ring worlds or sphere ones even if you could.
Well lets see shall we. We don't have to guess, and from intuition i do think your wrong.
First of all a Dyson sphere is *not* a solid sphere, the original speculation was lots of orbital satellites in a star orbit of sufficient density to significantly occlude the star. Lets assume a total of 50% occlusion maximum. It will be less on average because of the orbits of these power satellites will intersect and overlap from time to time.
Now since we are not a wasteful civilisation we set these things up fairly close to the star. Say 10 million km from the star center. Now the average thickness of a power satellite can in fact be very small, cus its 99% mirrors for example. Lets assume.1mm of material. Which material? Lets assume metal, in this case lets just try pure iron. We can in fact use many different materials. But that can work and gives us an idea of what our solar system could support.
So now the numbers: the total area is pi*1e9^2/2=3.14x10^18 m2. Total volume of iron is 3.14x10^14 m3. This is substantially less that the volume of just earths inner core at 4.27x10^18 m3.
So in short there are many orders of magnitude more material in the solar system than is required for a full Dyson "sphere".
Giving advice to prospective repeat customers more like. Lawyers don't make money off people who don't need a lawyer!
There is a reason that the centuries old joke of "kill all the lawyers" was and still is funny. And perhaps a little sad that the law profession has done nothing in the intervening years to fix that reputation.
You understand wrong. The ballmer peak is funny. But it is not science and it is *not* biology. It is quite easy to measure relevant motor skills with alcohol impairment. Every single person gets bad then worse then terrible.
Being the clever guy in the class, i modified the basic it was written in to be quite "boyish". Instead of wheat and stuff, it was sperm for the prostitutes. I forget the exact changes. Anyhow the girls in the class loved it (why i did it in the first place) and they played it with the teacher in the room and where in hysterics. So the teacher watched....
Well so much for being the smart kid. I was the only one that could code, so despite the girls pleading the 5th or whatever you do when your 12 in NZ, i was busted. Fortunately i had also just got into a lot of trouble with current crush of the month (she was tall and had amazing boobs in catholic uniform! ) by trying to hit on her with fancy things. Stolen things. Her dad was the local police constable. It did not end well. My parents didn't know what to do. So they did nothing!
Close enough. We expect slightly less than half a person to have a true positive. So it is closer to 1:800 chance that they have cancer. Wondering if anyone was going to answer. Btw that is the statistics of these 136 or whatever children that have not passed these tests. Mostly likely none of them have thyroid cancer.
My wife and daughter love the fast paced FPS like quake. In fact they where a lot better than many of my friends. It was a big deal to beat the family.
No they don't have 137 confirmed cases. They have 137 *potential* cases from a test that has a *false positive* rate. The quote are media BS "Dude on a phone said...". Show me the data. Real data, not "OMG Radiation!" Incidentally they don't even have that data. How many of the 137 were not exposed to *any* radiation?
It not a higher rate of cancer. It is a higher rate of *potentially* cancerous cells. But that is how screening works. Rather high false positive rates but generally much less invasive or cheaper than the more expensive test that has a low false positive rate.
Here is the test. I test 400,000 children for a cancer that has a prevalence rate of 1 in a million. The test has a.1% false positive rate. If my child tests positive what is the probability my child really has the cancer. Note most doctors get this wrong.
Having worked for big pharma, that is more than enough proof that patents should be abolished. Oh but it cost so much to get a drug to market you say. They don't pay for that, government grants and university "collaborations" do. But who will make our drugs? Well for a start we may actually get drugs that are useful and help, and will even be given only to patients that need them. Secondly we will get rid of the "Shut up and take our fucking pills" pharma medicine. It is like homeopathy. Only with real side effects.

All symmetric ciphers are resistant to QC. It is a mathematical fact. Numb nuts.

Can you fit more bullshit per character in a post? I don't think so.
At least read your own references.
Thats nothing. My great grand daddy doesn't like anything driving anything that doesn't eat at least 2 bails of hay a day and some oats.
Yet so many here seem to think a human driver can overcome physical laws. Apparently humans are magic.

It is still unstable. Spinning or not. It will fall "sideways" into the star.

Try reading at least the summary. It even points out that it is not likely. But also your suggestion is *worse* since it would be periodic. It is not.
And so are spheres. The original dyson sphere is not a sphere. What was proposed was in fact a swarm. There really is no reason to do ring worlds or sphere ones even if you could.

Hence why i want autonomous cars. And yet idiots like yourself probably are dead against them. Because "your the good driver" right.

You also had to change the animations. But meh. Your an AC. What have you done lately. Calculated a compound interest formula?
There was a very similar one for the BBC micro we had at school, the yellow river kingdom. https://www.youtube.com/watch?...

Lets also not forget the 20 meter tsunami that caused this nuclear incident killed or washed away the better part of 20,000 people. Children included.

or just a growth, aka like a wart. Our cells do that quite a bit throughout the body. It is why biopsy are needed.
is that you angle o sphere?

Burning all the big pharma to the ground would increase the health of the general public.
