As I understand things, without the calibration there would be 18 images overlaid each other with some shift in between. Each mirror has quite some degree of freedom, so they have to be aligned to each other until you have one sharp picture

JWST is expensive for two reasons. One is the giant heat shield, as it is an infrared telescope. There is no real way around that. Secondly it is the space in the rocket, the mirror (and everything else) had to be folded to fit into the roc

And it has to be remarked that Hyperloop was solely a concept Musk published to share it, as he personally had no plans of implementing it himself. The only other involvement of his with it is sponsoring a yearly event where universities ca

That is true, but currently most manufacturers use a system like the initial Autopilot, the Mobileye solution with radar and some camera information. LIDAR should be quite for collision avoidance in conditions where it can be used. This sho

Considering they sold 930k cars in 2021 alone, I would guess they have a good bit more of cars on the road now, but less than Mobileye. Radar, as we know from some Autopilot incidents, has problems detecting stationary obstacles. I sincere

Why would you assume that no office building would retrofit their parking structure when there are huge incentives to do so? For sure not all of them might, but if enough do, it will be a major benefit. But yes, if a car isn't connect

Which car manufacturer uses LIDAR in production vehicles? What they usually do is use radar. As Tesla did in the past. This is less likely to do phantom braking, but on the other side is bad at detecting stationary obstacles (remember all t

Considering how much storage capacity becomes available when connecting cars to the grid - even if the part used for grid storage is only 10kWh/car (typical batteries have 70 or more kWh) - I would assume there will be a huge push by u

Well, in the end someone has to pay the costs and that is the tax payer. That is why amongst the choices for energy production, the overall cheapest is the most popular. The state can help boost a new technology with subsidies, but in the l

Yes, if you run it over with an excavator, even a German power line will break :p That is what happened in the link you posted. So it has nothing to do with the energy production capacity in Germany. And there is little to fear in this resp

Of course, in Germany most houses have central heating and central hot water production in a room in the basement. A lot of them even have large oil tanks which could be removed for additional space. There are a few old Buildings from the

Yes, there needs to be more storage or backing by gas plants. But nuclear power needs the same gas plants as you cannot change the output levels quickly enough to drive the grid. In a sense, constant output is almost as bad for the grid as

With the meteor strike of Chelyabinsk, the dashcams did document it well - probably less of them in use in Tonga then in Russia :p. But one should hope that at least some smartphone was directed at the vulcano, especially as it had erupted

Thanks, I had always wondered why some sites behave differently with some file types. A bit annoying, if you just want to glance at something for a while but not keep it around for longer.

I am just wondering what is it that prevents that link to open the image in a browser window but forces a download of it?

Think about going over a bump. This gives the wheel a strong upward motion. The suspension has the task to discouple that motion from the car. Which is easier, as much as the wheel mass is low compared to the cars mass. Thus the aim is to k

Because corona viruses are a different kind. There have been no vaccines against them so far and we saw how strongly they mutate. Still, the 3-shot regime seems to be very effective against severe disease. They probably deliver as much prot

You are wrong. mRNA covid vaccines don't "only work for 90-180 days". First of all, you need 3 shots to get fully vaccinated in the first place. This is one shot more than the original approved plan, but a very common thing a

Higher costs for the provider translate into higher costs for the customers.

Price, simplicity. 8m mirror size would equal some of the largest telescopes currently on the ground. A lost of cost could be saved, if the whole teslescope could be completely assembled on ground. Later iterations could have larger mirrors

If it is the noise, where all attacked ships running under engine or where some of them sailing? The sailing boats wouldn't make any especial noise. Unless the Orcas developed a sudden hate for all boats.

I was quite surprised when I saw the first reports of that and find them equally faszinating and terrifying. I am wondering, what started this behavior by the Orcas and whether this is in any way connected to them increasingly killing other

Yeah, 27" iMac owner here, desperately waiting for an upgrade. If Apple had been a bit more open about the road map, I might have bought an air around the release date to bridge the time till the iMac update. Wouldn't say no to a

I am quite relieved that all the deployment worked out and so looking forward to the first images. I hope, planning for a true Hubble successor (a telescope in the visual range) starts soon. Maybe a one-off Starship could be the telescope h

Depends about which compiler you are talking. I think there are very specialized Fortran compilers which produce excellent code for scientific applications.

I disagree to the blanket form of statement. Yes, it is the feudal lord who does the killing, but that doesn't mean there is no guilt if your actions effectively lead to the named peasants are killed. Whether one shares some guilt by t

Obviously, if one person is really 100% remote, there is no direct infection risk. But this might not apply to most employees, there are probably a lot, which mostly work from home and still meet coworkers or customers from time to time. I

I can understand the difficulty of Mac ports, if a game doesn't support Metal yet, but that is the case with StarCraft. In theory, a recompile might do.

I wonder what this means for the classic IPs of Blizzard, like WarCraft, StarCraft and Diablo. Especially StarCraft could use an update - I would immediately buy a SC III for the Mac. Unfortunately, there was no update since SC II was porte
