None of that is possible without digital computers and those generalize to a much larger domain of devices and technologies that have revolutionized the world in thousands of ways. So no, the smartphone has not had a larger impact on the wo

The smart phone doesn't even belong in the same category as the others you listed. The digital computer certainly does but it's been 80 years since that occurred. The smartphone is simply a refinement of that basic technological l

Spent fuel rods are a much safer destination for radioactive material, much better than particulate matter released into the atmosphere.

If wiping is the main problem you could just wipe them with a cloth or some other device. They are exposed and highly visible after all.

I don't see why the contacts on the demonstrated devices would be any more vulnerable to the real world than the port on an iPhone. I'm not sure these devices would be mass market since some skill is required to understand and use

Changing the Earth's albedo at the surface would be more controllable than pumping a bunch of particulate matter into the atmosphere. Probably a lot more expensive as well but the tradeoff is worth it since it would allow you to quickl

It reads more like a humorous and self-deprecating aphorism to me. He was a comedian after all.

I think the second link with the collimating lenses is more what's needed. I was just looking at another page and saw that you can also buy collimating reflectors which might be cheaper than lenses. I wonder if that's something yo

You'd also be changing the focus of your eyes nearly constantly as they saccade from one object to another. I agree that it's ridiculous using a study like that as a way to dismiss the conventional wisdom that staring at things cl

The dangers of having a very strong point light source are, I think, a good argument for distributing the lights across a large area. Since distance matters with light intensity it would also help to never be very far from a lightsource whe

Would be nice to find somewhere that sells these lenses in bulk, from a quick search they seem to be quite expensive.

This is exactly the rebound effect. The Wikipedia article unfortunately makes it out to be a Bad Thing and frames it as a wasteful increase in energy usage. It clearly isn't if you look at the given examples or think of some yourself.

Those sub $1000 options from daylite don't look very bright, despite the reviews they have very few images that show what they look like in a room and the ones they do have look like a regular LED panel stuck on the wall. I doubt this

The wind force on Mars is not very strong, the surface pressures is only 0.6% of Earth's and the top windspeed is around 100 km/h or 62 mph.

If we converted all energy production to geothermal, would it be possible to significantly increase the cooling of the Earth's core? The flow from the Earth's core to the surface is estimated at 47±2 terawatts[0] The total energy

Considering that Putin came to power in Russia's first (and possibly only) democratic election, I'd say a lot hinged on his view of how the West would treat them. Sentiment at the time was that he enjoyed an unfair media and power

I think the freedom of an untethered headset is a big selling feature, at least for people who have used both tethered and untethered VR headsets. Since the Simula has full color passthrough, it should be easy to get up and make a cup of co

Maybe I'm optimistic, but these are just problems to be solved. Space exploration is a big risk / big reward investment. Yes it would require a comparatively huge investment to mine an asteroid vs. open a pit mine in Brazil but &q

I'm of the opposite opinion. I think we need to spread out as soon as possible because it's not clear we can ever completely future proof our civilization here. There are simply too many things that can go wrong, many of which are

The main point of the article seems to be that because we are the only branch of life on our planet that became multicellular and started reproducing sexually that it is unlikely that this ever happens. I think that neglects the possibility
