Kotaku, the Guardian, NYT all send you to their amp page if you surf there from Google search. Just click any link that says "amp" next to it. So I obviously googled about this amp thing and it is quite the irony how badly their own pages about it render on my phone  | ||

Like did he say what he did wasn't racist, that he's changed, or something else/some combination? | ||

You have the plane standing still with spinning wheels. Creating no lift due to standing still and not moving through the ground level air at speed. | ||

Can the plane take off? no. lift is based on speed compared the air right? so since the plane is moving nothing compared to the speed of the air around it it has no lift. I'm not an expert but that seems pretty obvious. It's like saying. a guy is pushing a car that won't move, how much work is he doing? | ||

The actual answer is that the question is fundamentally flawed and that I should feel bad for asking it. There's no way to "have the conveyor belt match the speed of the wheels". If you make the conveyor belt move faster, the wheels will just spin faster. Generally this question is pretty good at getting increasingly hostile and condescending responses from both sides though. | ||

Flawed questions are best in showing people's characters Nice to see this explanation this early after it has been mentioned!the best show of human idiocy is when tricky questions are posed for a general audience and people keep coming in and stating their opinions as a solid fact, openly ignoring the other responses that already explained the trickiness. | ||

I was thinking of your GMO antics + Show Spoiler + On January 12 2017 15:23 Cascade wrote: I'm trying to understand here... Are you afraid that: 1) GMO plants will happen to have DNA that cause Parkinsons in humans, but the wild type plant doesn't. 2) We eat the GMOs, and the DNA somehow doesn't get digested, because hipsters don't digest DNA. 3) The GMO DNA makes it way up into the brain. 4) the GMO DNA somehow gets into all or most of the cells in the brain. 5) The GMO DNA somehow manages to slice its way into our genome in the nucleus. 6) In a way so that the GMO DNA is actually expressed into protein. 7) This extra copy of GMO DNA has a dominant effect over the naturally occurring gene. 8) But all this only happens only to that new piece of GMO DNA that codes for the Parkinson defect. The brain doesn't otherwise turn into a plant. I guess not, but I'm struggling to get my head around what you mean. That said, I really do wish biomedical science was much more open. Few things get me as riled up as IP shenanigans blocking sciencific progress. :/ | ||

Few things get me as riled up as IP shenanigans blocking sciencific progress. :/ i've been reading about some depressed dudes in here and found http://www.nature.com/news/sperm-rna-carries-marks-of-trauma-1.15049 Trauma’s impact comes partly from social factors, such as its influence on how parents interact with their children. But stress also leaves ‘epigenetic marks’ — chemical changes that affect how DNA is expressed without altering its sequence. A study published this week in Nature Neuroscience finds that stress in early life alters the production of small RNAs, called microRNAs, in the sperm of mice. The mice show depressive behaviours that persist in their progeny, which also show glitches in metabolism. ...In the new study, Isabelle Mansuy, a neuroscientist at the University of Zurich, Switzerland, and her colleagues periodically separated mother mice from their young pups and exposed the mothers to stressful situations — either by placing them in cold water or physically restraining them. These separations occurred every day but at erratic times, so that the mothers could not comfort their pups (termed the F1 generation) with extra cuddling before separation. so if they can't/won't get cured, at least they should not breed.When raised this way, male offspring showed depressive behaviours and tended to underestimate risk, the study found. Their sperm also showed abnormally high expression of five microRNAs. One of these, miR-375, has been linked to stress and regulation of metabolism. The F1 males’ offspring, the F2 generation, showed similar depressive behaviours, as well as abnormal sugar metabolism. The F1 and F2 generations also had abnormal levels of the five microRNAs in their blood and in the hippocampus, a brain region involved in stress responses. Behavioural effects persisted in the F3 generation as well. or, i can even pin "a fetus is a human being" on this and be right; it understands/shares my pain!. Edit: or refugees, war refugees. they would have depressed/stressed, fearless children prone to act up. | ||

Generally this question is pretty good at getting increasingly hostile and condescending responses from both sides though. I disagree. While the conveyor belt is moving, it will also accelerate the air above it in the same direction due to friction. When the plane stays stationary, this means that there is airflow around the wings. The plane can lift off if the conveyor is running fast enough, while staying stationary above the turboconveyor. Basically, you have created a wind channel. | ||
