I'm also addicted to the fan but not only for the noise I like feeling the wind in my face, I think that as it also helps lower your body temperature you sleep better
The study may well be flawed—small n, selection bias, lack of proper controls, sure. But can we please stop using personal anecdotes to dismiss scientific inquiry?
Arguments like 'well, it works for me,' or 'I took this med and recovered immediately,' or 'I saw X happen right after a vaccine' are not valid refutations. Science is frequently counter-intuitive and often contradicts our personal experience and gut instincts. That is precisely why we rely on the scientific method and statistical rigor—rather than individual perception—to establish evidence.
On the other hand, my life isn’t a double-blind randomised controlled study.
I can’t bifurcate n times and give half of the me’s one treatment and the other half of me’s no treatment, and I especially can’t do that without revealing to myself which group of me’s received the treatment, and which received no treatment or a placebo. Who even know motivates us.
Additionally, what works for some version of me, for example there was a me who was younger and fitter and more appealing to the ladies, may not work for the older version of me who is less young, relies on testosterone supplementation to not be a writhing crying mess on the floor, and hasn’t had a root in 18 months.
That’s why the practice of medicine has always been considered an art and a science.
There’s art in learning to apply the practice of medicine in an effective way.
Also, populations change over time. Older doctors will notice that decades ago every second person came in with problem x, but now the patients of a similar age and similar live experience now seem to be experiencing more y and less x.
The human condition, while at least somewhat consistent insofar as we’re still puzzled by some age old questions, is also a moving target.
This study is tiny and of negligible value. They didn't even try to pretend it's of real value, and instead just dropped the classic "our study clearly demonstrates that people should probably study this stuff". Conditioned norms are by far the most relevant condition for sleep for most people, and sleep studies of tiny durations with tiny sets are basically just noise makers (har har). Even worse, they seem to have specifically excluded people who already use noise machines, ensuring that their participants were conditioned for the silent norm.
Scientific method, statistical rigour...eh, this looks like a headline chasing study.
I used to get a cold around every 6 weeks from working with people and being in the office with freezing airconditioning all year round. Since working from home I haven't been sick in two years.
I'd hate to be a carrier pilot and the helmet fails on blue water ops, you can't land, only option is to go for a swim. And single engine too over water... hmmmm no thanks.
No backup instrumentation either.
A lot of the references you use to land on carriers are outside the aircraft, and the process is becoming largely automated. Besides, we've been flying single-engine aircraft blue-water for decades--it's not THAT bad in the grand scheme of things...
Carrier landings should move eventually to JPALS (all-weather landing system) in some time in the future. It's military Autoland that works even for carriers and amphibious assault ships).
I was going to comment on it but did search first and found your comment. It is hilariously funny but more to the general theme of HN is a notable example of a typo that cannot be caught with a simple spellchecker and probably not even more complicated grammatical checker, but some kind of neural network maybe?
A330 has figured in the incidents, but AFAIK the flight control software and angle of attack sensors that are implicated in those incidents are the same in all of the Airbus models.
> They never quite figured out the root cause of the un-commanded dives
Yes, they did. Read the "Conclusion" under the "Final Report" section. The "design limitation" they're referring to is that, first, the autopilot is not driven by an average or majority vote of the three angle of attack sensors, but by one of them only (which one depends on whether the captain or first officer's position engaged the autopilot), and second, the other two angle of attack sensor inputs are not used to check the sensor that is driving the autopilot, so if that sensor gives faulty input (the "multiple spikes" described), the faulty input is allowed to trigger uncommanded events such as the violent pitch down that happened on Quantas Flight 72.
What should happen is that the input from all three angle of attack sensors should be combined: as long as all three of them are within some tolerance, the average of the three becomes the angle of attack used to drive the autopilot. If one goes out of tolerance compared to the other two, its input is discarded until it comes back into tolerance (so "multiple spikes" from one sensor would simply be ignored). If it takes too long for the one sensor to come back into tolerance compared to the other two, that sensor gets ignored for the remainder of the flight and the pilots get notified. If it gets to a point where no two of the sensors are within tolerance of each other, the autopilot gets disengaged and a big red light goes on in the cockpit. I am unable to understand why that is not how the system is designed, but the investigation reports make clear that it isn't.
The first and second report look to be the FO's and Captain's for the same incident. And don't make sense as I though MCAS is during manual flight. Why would Auto Pilot need MCAS, it's like Auto Pilot using Auto Pilot?
I can't help think ETOPS are going too far. One day a big twin will fly from Sydney to Santiago and develop double engine trouble and the 3-4 engine minimum will be mandated again.
It's not about being lazy, it's a huge help if you are multi-tasking and are time poor ,like most parents are. A pretty normal scenario for me is trying to get the kids out the door, whilst doing their shoelaces you tell Alexa to turn off the tv, turn off lights, tell you the weather forecast and when the next bus is due to arrive out the front.
This is just like the Brexit vote. The populous doesn't know what they are voting for. When they realise all that daylight at 4:30 AM is wasted while they are sleeping it will be too late. As others have mentioned a lot of the DST opponents are confused and actually hate the switch from DST to standard time. I love DST I look forward too it every year.
My mum would try to stop me playing this because it was too violent. The prisoners getting whipped in the dungeon really apalled her. Violence has come a long way since then.
I must admit that I stopped watching this video at the scene where the prisoners are getting whipped because I found it upsetting. I watch Game Of Thrones and have played violent video games. So I'm not your Mom. :)
Perhaps the audio is just too clear ? Or perhaps there isn't enough going on scene-wise to distract. Or just the fact that the whipping is perfectly periodic and programmed to go on indefinitely. I don't know.
