How can it be that we can still see the CMBR?
John Cuthber replied to Rolando's topic in Speculations
"How can it be that we can still see the CMBR?" Where could it hide? -
Why are tropical fruits generally much sweeter than temperate?
John Cuthber replied to studiot's topic in Biology
Looking at the data so far, the only gut we can rule out as the delivery mechanism is a human one. -
The question "Science proves or increases the chance for a God to exist?" makes no sense. God exists , or he doesn't. Science can't influence that so it can't increase the chance that He exists.

It still tastes like beer. Of course, if you were in the US 10 years ago it would (famously) have tasted like "making love in a canoe".

What does dark beer taste like? It tastes like beer.

If cattle had been "planting" nightshade in your allotment , I think you would have noticed. Evolving an atropinase enzyme just requires tweaking some other esterase. It will prevent damage by a range of toxins. Learning to avoid nightshade would only avoid one. -

Some rabbits are substantially immune to deadly nightshade https://en.wikipedia.org/wiki/Atropa_belladonna#Toxicity -

Strictly speaking,you are mistaken; they still vibrate. It hardly matters here. -
Ok, I presume that's typo and should say ""brain not working.". Interestingly, it's in quote marks, but not a quote. Whatever... Would you be able to drive a car in those circumstances (i.e. full of drugs)? If not, would it be because there was a problem with some other organ- or would it be a problem with the brain? That's all evidence that so called "religious experiences" are a (fairly common) feature of the brain being disrupted rather than intervention by any God
-
You have just posted strong evidence that so called "religious experiences" may be drug induced hallucinations. Another way to look at it is that the brain doesn't work properly when it's full of drugs. So it looks like religious experience is either what happens when the brain isn't working, or at least, it's something very much like it. That's evidence of a brain failure, rather than the existence of God, as the cause of religious experience. Other evidence also exists. https://en.wikipedia.org/wiki/Temporal_lobe_epilepsy#Link_with_religiosity

I suspect that the permitted body burden for 210 Po is a few orders of magnitude less than 1µg. The value I found online was 30 nano curies, or 6.8 pg. And you would need to start with roughly 10Kg to make a MW generator. Each SI prefix is about 10 half lives (2^10 is about a thousand) so A nanogram would be "safe" after 10 half lives a µg after 20, a mg after 30, a gram after 40 and a kg after about 50 half lives. Something like 18 years before the original 7 Kg that emits a megawatt decays to the 7pg or so that's a permitted body burden. This is of course a pointless discussion. World production of polonium is only of the order of 100 grams per year https://en.wikipedia.org/wiki/List_of_world_production So it would take 100 years to make 10Kg, but that would have decayed about 82 years before you finished making it. This idea is dead.

Are transistors the fundamental components of all computers?
John Cuthber replied to Achilles's topic in Computer Science
You can also use relays- they are slow + power hungry. -
Unfortunately, it seems the only insight it brings is to your willful lack of understanding.

The last figure I saw said that 42% of US households have a gun. I suspect that the states where "stand your ground" laws are in force have higher ownership rates. That would be relevant if I had said that most people would kill people using this as a precedent. I didn't. True, but there are plenty of cases where people kill their neighbours. This case makes it easier for some of them.

According to the wiki page https://en.wikipedia.org/wiki/Polonium#Applications "Because of intense alpha radiation, a one-gram sample of 210Po will spontaneously heat up to above 500 °C (932 °F) generating about 140 watts of power. " So, getting a million watts will take 7kg of the stuff. So the assertion implied in the thread title is absurd. We do. You do not.

Actually, it's exerted in all directions. -
That's tens of thousands of curies of radioactive material. Even if we ignore the terrorist threat from a dirty bomb, there's a huge risk of radioactive material leaking from a car crash. Why would anyone take the risks?
