Japanese Scientists Fire the Most Powerful Laser On the Planet 111 111

Sepa Blackforesta writes: Scientist from University of Osaka claim have fired the world's most powerful laser. The beam was intact for 2-petawatt, pulse lasted just one picosecond. While it produced a huge amount of power, the energy required for the beam itself is equivalent to that needed to power a microwave for two seconds. An associate professor of electrical engineering at Osaka University Junji Kawanaka says “With heated competition in the world to improve the performance of lasers, our goal now is to increase our output to 10 petawatts.”

I've seen tons of 17" and 19" 4x3 LCDs, as has probably everyone else here older than the age of 14, but I couldn't tell from a distance what the native resolution was, or whether the pixels were square or not. That's the kind of thing I'd check with a test image or a magnifying glass, to verify published specs. I also don't think I've ever personally seen a physically 5x4 LCD (or CRT, for that matter), which a 1280x1024 resolution would require, in order to have square pixels.

Ok, maybe I should have taken my vitamins this morning. What I meant to say was: I agree that there's no use case for biometrics in my proposal or in the original arrangement. The rest of it was in reference to the original arrangement, where I think biometrics are overkill.

Yeah, that would work too. I don't see any use case where biometrics are necessary, if it isn't essential that exactly that particular kid and nobody else is to use a service. But this is elementary school, so I'm sure the kindergarten teacher or whoever will be able to vouch for a kid if the lunch lady decides to go to defcon 2 because the kid has no arms or something.

Dude, no. What I'm suggesting is that Google could partner with a bunch of restaurants, where Google would pay for the orders made by people, and collect the data. Then the companies could subscribe to the entire data pool from google, and get valuable consumer information. Kids get free lunches, companies get data, and google gets revenue.

It just occurred to me that this kind of thing would provide useful data to fast food companies, if used in the general population. Imagine something like "Google Lunch", which would provide a free meal to people who swipe their thumb. One would think that the data on where, what, and when people prefer to eat would be worth some serious money to those companies.

I haven't hit that problem yet, but I think they could do a better job with the auxiliary content on the site. For example, This is what I get for "Related Links", at the bottom of the page:

- Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days
- Man Booted From Southwest Flight and Threatened With Arrest After Critical Tweet
- Russian Military Forces Have Now Invaded Ukraine
- Professor: Young People Are "Lost Generation" Who Can No Longer Fix Gadgets
- Oregon Testing Pay-Per-Mile Driving Fee To Replace Gas Tax.

I have no idea what their criteria is for "related". Also, there used to be a "post" button at the bottom of the page; now I have to scroll all the way back up to the top to post.
