Comment Can you stand of this planet? (Score 1) 87

I'm hoping someone better at math than me could answer this question: if we visited one of these exoplanets, if we landed and a person was to stand on the surface, would they be thrown off by the centrifugal forces from orbiting its sun that fast? would the difference in force between the sun side and dark side of the planet be noticeable when you're that close to the star?.

I've heard about exoplanets being habitable up close and very fast orbit around a cool star, and wondered about the forces you'd experience. I've read that on Earth you feel ~2N from centrifugal forces, but ~590N in the opposite direction from gravity.

Can you stand on this planet? ignoring radiation, atmosphere, temperature, etc, just based upon the forces on the body.

In Australia the rules are:
Under 10 days: Bank takes the money back immediately
Between 10 days and 7 months: Bank freezes money and gives you 10 days to prove it is yours.
After 7 months: You can be asked to return the money, but it is legally yours now.

Another complicating factor is that the period they measured to determine the water allocation, was the wettest period in hundreds of years.

"The new research also confirms that using stream gauge records alone may overestimate the average amount of water in the river because the last 100-year period was wetter than the average for the last five centuries..... The long-term perspective provided by tree-ring reconstructions points to a looming conflict between water demand and supply in the upper Colorado River basin," the researchers wrote in their report." https://news.arizona.edu/story...

Submission + - AI helps French tax collector spot evaders (theguardian.com)

Bruce66423 writes: 'French tax authorities using AI software have found thousands of undeclared private swimming pools, landing the owners with bills totalling about €10m.

'The system, developed by Google and Capgemini, can identify pools on aerial images and cross-checks them with land registry databases. Launched as an experiment a year ago in nine French departments, it has uncovered 20,356 pools, the tax office said on Monday, and will be extended across the country.

'Modifications to property, including adding swimming pools, must be declared to the tax office within 90 days of completion. As property taxes are based on the rental value of the property, improvements mean an increase in taxes. A typical pool of 30 sq metres would be taxed at about an extra €200 a year.'

Seems fair to me!

Submission + - SPAM: A New Energy Storage System Is Able To Store Solar Power For Nearly Two Decades

RickyFrancis writes: The technology was created with specially-designed molecules of carbon as well as hydrogen and nitrogen. These molecules are exposed to sunlight and the atoms in them are rearranged. This produces an energy-rich isomer in liquid form. Amazingly, researchers say their technology conserves energy in liquid form for up to 18 years. The catalyst that is specially designed releases the energy, bringing the molecules back to their original form and releasing it as heat.

Submission + - In life's origin, what came first, the metabolism or the information storage? (quantamagazine.org)

Beeftopia writes: All living cells power themselves by coaxing protons from one side of a membrane to the other. A place where this occurs naturally outside of cells are alkaline hydrothermal vents on the deep seafloor, inside highly porous rock formations that are almost like mineralized sponges. "Carbon and energy metabolism are driven by proton gradients, exactly what the vents provided for free," wrote biochemist Nick Lane.

In Lane's view, metabolism came first, and genetic information emerged naturally from it rather than the other way around. Lane believes that the implications of this reversal touch almost every big mystery in biology, including the nature of cancer and aging.

The reversal of the Krebs cycle in some cancers came as a shock because it was thought to only ever run in one direction, forward, to generate energy. In aging this reversal may play a part as well. Gaining control over this factor may lead to improved outcomes in both cancer and aging.

It unreasonable because its their room, their house, their private space. As the court ruled, there is the expectation of privacy in your own home: "Mr. Ogletree's subjective expectation of privacy at issue is one that society views as reasonable and that lies at the core of the Fourth Amendment's protections against governmental intrusion," Calabrese wrote in the decision.

I've been working from home about 12 years now, there is no chance I'm taking any job that requires me to be in the office. When I gave up my commute, I couldn't believe how much I got done in my personal life, all those hours in a car, were mine again.

Our company started unlimited time off and wfh this year as they have been unable to attract any young talent in the USA. All the college grads (mostly engineers) we try to recruit all want "unlimited time off".

The big part that makes our company different than most I've heard of, is that the managers are actually being evaluated on their teams actually taking time off. The expectation is that you should be taking more time off than you did over the last years. The main part that won everyone over, is not the "unlimited" part (managers still have to approve time off), but that you can easily take an afternoon off when the stress is too high, or you have an appointment, etc.. If I don't have any meetings after lunch on Friday, I wrap up early and start the weekend.

Comment Re:non refundable reservations (Score 1) 52

Nothing new here. Its the same with Airlines. I don't think I've ever booked a non-refundable room for my own trips. For work yes, but thats their $$ not mine. For my own holidays, I always get tickets, rooms, cars, etc. that I can change. Far enough in advance, the price difference is usually not that much. Once my Mum came to visit me in the USA, and had problems with flights because she booked non-refundable ticket. It was only solved by me buying another day-of ticket for her :-(

For those unaware, never book a holiday with multiple flights, separately. Say your international flight arrives late and you miss the domestic flight to your final destination. If the tickets were bought separately, you now need a new ticket, as both airlines say the are "not responsible" for the situation as they didn't know about the other flight. If you book your flights together, then when the international leg is late, they are responsible to fix the connection issue because they knew you had the connection.

and don't rely on travel insurance!

Anytime I've been asked for any biometric data, I always respond with "no thank you" even when it makes no sense based upon what they just said. I've had Airlines, Hospitals and Hairdresser asking me to use biometrics to "make things easier".
How is facial recognition easier for boarding a plane than scanning a barcode as you walk onto the jetway?
Why would I give a hospital my palm print to identify me, when they still scan the barcode around my wrist?
wtf does my hairdresser need any biometrics ever?.

What I find most disturbing, is that when I object, they're confused by my response. So far no one has said it was mandatory. At the hairdresser, I saw many people arriving and being told about the biometrics and blindly gave it to them SMH

I've got mild ADHD and I take a stimulant daily, and it calms me down and allows me to focus. For my friend with severe ADHD, several drugs that affect the central nervous system behave the opposite to him. Pseudoephedrine puts him to sleep, while diphenhydramine wakes him up.

the science behind this is pretty solid, from wiki: ADHD is now a well-validated clinical diagnosis in children and adults, and the debate in the scientific community mainly centers on how it is diagnosed and treated... Stimulant medications are the most effective pharmaceutical treatment.[23] They improve symptoms in 80% of people, although improvement is not sustained if medication is ceased..
