There is a very large difference between building complex tunnels and a simple hole in the ground. The cost for drilling a straight exploratory/mining hole was 10 Million/km in the 70's…

Blue LEDs, and the more general Gallium Nitride film technologies have tremendous impact in our everyday world. Enormous, tangible energy savings in lighting. Enabling of zillion medical applications.…
comment
First of all, they acknowledged the conflict of interest. Are you suggesting, based on zero evidence, that their findings were somehow fabricated - a claim that if true would ruin the careers and live…
comment
I read the article more like: IF you want to be successful, here is this great advice. Like you point out, being "successful" is not everything, nor necessarily related to being happy. That …

Not at all. Inches have a direct relationship to a physical quantity.

Do you have a reference for the main sources of microplastics? My understanding is that they are the result of larger chunks of plastic that just decompose in the oceans. By removing large plastic ite…

Elsevier wants me to pay $40 for this publicly funded work.
Here's a direct link:

I guess the message is that what the author is sharing is common knowledge since the 70's. With the invention of the electron microscope people started looking at everything, including leaves, di…

This trick only works for bosons
*Edit: I think. At any rate, these depths of physics are quite complex and not very intuitive, and this kind of discovery shows it is very easy to overlook things. A g…

In addition to hardness, they have an exceptionally high thermal conductivity.
comment
Thank you for the link, this is quite interesting.
If I may ask a stupid question, wouldn't this imply that cancer rates should be lower in tropical countries, where the ambient temperature is c…
comment
Isn't this the point of the article though? that most people thought just like you, that the interaction would be miserable and a waste of their time, yet they were enriched by it?
comment
Maybe I'm missing something but in space you can have power night and day if you are using mirrors, and you don't have the atmosphere. Solar power in space is 1300W/m^2, whereas average…

Kind of like an all-software Lytro

Just to make it clear: perfect and perfectionist are very, very different things. You cannot paraphrase one into the other at all. In order to asses whether it's an stereotype or not, we have to …

I don't know what you are talking about with this whole tangent. All I gather is you have something against Japan that precludes discussion about it.
comment
Indeed, I have a large problem with giving my money to somebody with whom I hold partly responsible for the deaths and misery of hundreds of thousands.
I have a large problem with giving all my data …

That would be a strong argument if you would provide some sort of evidence.

But there are no definitions of Latin America that do not include Guatemala:
a) Former Spanish colonies
b) Spanish speaking countries
c) Romance language speaking countries
d) Countries South of the U…

I'm also surprised, 1 million sounds like a lot of money for such a thing.
comment
Sort of, except in that analogy people like Dijkstra and Knuth are saying "this is a big deal, let's take a closer look".
comment
I think it's due to expectations. Every single time I read about psychology research there are these glaring gaps in methodology that completely nullify their experiments.
After losing track of …

This comment is irrelevant and has high potential for derailing the discussion off-topic. Mr. Baez here is a world class mathematician; surely he is more than familiar with formally undecidable propos…

I'm sorry, I completely misread what you wrote!
comment
Indeed, he went to Bristol and Cambridge, whence he developed his relativistic quantum theory. He relocated to Florida towards the end of his life. *edited the part where I assert OP was wrong.
comment
Honestly I prefer to die.
