8:00 somebody in free fall already experiences weightlessness. As a matter a fact, that is exactly what the ISS does. It's in a perpetual fall to the earth but never reaches the surface due to it's speed. also: Total recall 2012 shows what will happen If You Fall Through The Center Of The Earth.
That statistic of 4.6% should be more explictly phrased. Of all deaths in the usa, of all gun deaths, Of All deaths caused by stray bullets, 4.6% are from celebratory shots. Since no exact number was provided, it could be as low as 1 person out of 20 stray injuries or deaths. Or 46 people out of 1000 stray bullet injuries or deaths.
One thing you didn't mention, is sex before bedtime. I've heard that it is excellent for the production of melatonin, and hence a good night's sleep!
Heh. This video does do a decent enough job in debunking a lot of myths, but also perpetuates a few at the same time. - For example, the fire in the bunker was not the cause of the ship going fast, it was burning the same amount of coal the ship would otherwise have been using regularly, and much of the coal in Bunker E was unburnt and *transferred to other bunkers* to isolate the fire, which was put out a day before the collision. Interestingly enough, this may have saved Titanic from capsizing as the mass of that coal not being there when the water flooded in. - Another is the binoculars. That would not help at night at all. Binoculars are used to identify something *after* the lookouts have spotted it. They typically are not used because while they magnify far away objects, it greatly narrows your field of view. Combined with the pitch black from a moonless night and the sea being as still as a mill pond, it's unlikely having binoculars would've helped much, if at all. - Tiller rudder orders were still very much in use at the time, sailing and steamship alike, and all the bridge crew was fully aware of the usage, and changes weren't made until much later. In fact, the next order First Officer Murdoch gave was hard to port so that the stern would swing out and the ship's stern would clear the iceberg as well. Had Quartermaster Hitchens not understood or been confused, this maneuver wouldn't have worked and whole starboard side of the ship suffered damage, resulting in Titanic flooding so rapidly it would have capsized and sunk in minutes, likely killing everyone onboard. Finally, the real problem with the Gardner "theory" is that the damage to Olympic was not that bad, as third party inspectors had determined how bad it was, and there are even plenty of photos taken of it in drydock. On top of that, White Star Line in the past had ships that were damaged far worse repaired and back in service, the most famous example of this is the RMS Suevic, which became grounded on a rocky shoal. The ship was partially freed by blasting everything loose from the permanently suck bow, having another bow built, then attached at Harland & Wolff shipyards. After having done such a monumental feat of salvage and repair, why wouldn't they do that for Olympic? The killing of Federal Reserve opponents also falls flat because there's no indication of anyone claimed to oppose who actually did. In fact, one of those cited, Isidor Straus, was actually in favor of a Federal Reserve!
Different situations different solution that the sulotion
Great video, and very nice explanations. High explosives at 8km/s is so ridiculously fast, I believe there are some at 10km/s as well. It's so much fun and fascinating to watch detonations and observe the sound delay etc.

Wind. A single word can summarize this 11min video
The record is rotating the wrong way! :)
This is going to be useful in planning, um.... nothing...
So.... With the difference in rotational speed at the poles and the equator, what would happen if a person was suddenly teleported from one to the other Would the airspeed slam into them and pulp their insides???
I too respond violently when awaken. And I don't even sleepwalk
Watching this at the airport travelling from switzerland to Los Angeles ^^ Lets see which way is faster (if any)
Ah, it was exactly what I thought 😊
WHEN GOD CREATED MAN THEY WERE NOT PRIMITIVE ACCORDING TO HUMAN EVOLUTION THEORY WHICH THEY HAVE KNOWLEDGE SAME GOES TO THEIR DESCENDANTS
Interesting question: If SpaceX Starship Earth to Earth ever happens (I'm doubtful), would flights on it be faster in the East to West direction due to the carousel explanation, since air currents wouldn't have a heavy impact on a rocket's flight path? Conservation of momentum does very much exist, but we have to remember we're talking about a sphere. Without modelling in the atmosphere the hovering harrier would have to travel a longer distance through a full rotation of the Earth, so if it was able to hover perfectly vertical the entire time the momentum conserved from taking off from the Earth wouldn't be quite enough to complete a full rotation, say, 500m off the ground in the same amount of time as Earth. Albiet obviously that's a small enough change for a human pilot to easily correct for very slightly and by using the environment as reference points... But if we're talking about rocket travel, well first of all the peak altitude is higher, the atmosphere isn't that much of a factor in speed, and we're not considering a "hovering" scenario. I'm legitimately curious if the situation would be reversed for them (and my experience playing Kerbal of having rockets launched straight vertical usually drifting west a bit whilst in space is telling me it's likely).
dinosaurs are birds and are extinct for evolution to fly
I think it has to do with relativistic effects from Einsteins equations… 🤔 Honestly, a very good explanation and definitely a “flat earth killer”.
Can't believe you didn't draw attention to one of the most important differences between running or walking in the rain. If you run, you might get a little less wet but you will be wet in more places. You get a lot more rain drops hitting your front, whereas by walking most will drop on your head (of course the angle of the rain etc. are relevant here but the general point remains). So this is for me one of the two decisive factors. Do I prefer wet hair or wet pants/shirts? The other factor is my gut feeling about how much better/worse the rain will get in the time it takes me to walk to my destination.
As a drone operator, I figured this one out by myself 😂
Wind current? Common sense.
Nice video! I have one doubt. At minute 5:44. Why does the hot air go north (and south also I guess)?
Air is heated up at the ground, rises up, therefore increases pressure at high altitudes. Less air north and south -> wind from high pressure to low pressure
@@icefreez3r815 makes sense. Thank you!
Umm...jet stream? Edit: Oh, okay. In the first minute or so of the video I thought it was going to try to explain the flight time difference with rotation. I'm glad to see it went the right way.
Raining cats and dogs
SO ....the answer is the blue whale....nobody cares about trees and fungus
Great explanation as always.
Thank you 😊
Nah I refuse to believe this evolution amd strange creature have proven science incorrect throughout time. Sure none of them existed obviously but could that mean never? I mean probably lol. But we got creatures that replicate themselves and survive the vacuum of space.
if slower means better, you should stand still in the rain.😊
Two Icelands on the globe :)
Wow
Your record player is rotating in the incorrect direction.
It is very simple. If you fly to from London to New York it takes longer because London uses the Meric system and we here in the states don't.
Another physical effect not mentioned in the video is that flying eastward results in a greater angular velocity compared to flying westward. That's because the angular velocity of the plane is added to the angular velocity of the earth. This results to an increased centrifugal force, reducing the effort required by the engines to maintain the plane's altitude. The effect of this phenomenon at reducing the duration of the flight is minuscule compared to the effect of the winds.
I was recently thinking about this 😮😮
You're amazing, great job!
Thank you so much 😊 Glad you enjoyed it!
What's our vector, Victor? kzread.info/dash/bejne/mIqllsGBmKWxaLw.htmlfeature=shared
Nice portable clock devices located on your wrest
I wish I could just destroy internet, or infestate it with virus that will copy it self endlessly to the point that internet would be unusable.
i wonder if the space elevator concept will ever be realize...
We did that in 10 minutes in ISS and Space Shuttle..
ha ha! fly across the Atlantic in a 230mph C-130 and discover what a long, loud flight really is like
Irrelevant talking about inertia in your anology about someone jumping in the air on a conveyer belt as planes are in the air way longer than the person jumping.
Facepalm
Thanks for that insightful response Dunning Kruger.
Oh dear, there's always one.
You DO realize that you gave "Flat Earthers" more fuel...right?
You'd only think that if you're an idiot
😆
Not really. The difference in flight time is explained by the Coriolis Effect, which can only happen in a spherical, rotating Earth. In a flat, still Earth there is no reason whatsoever for the flight times being different.
@@MariaMartinez-researcher No, it was thing thing where he is using an LP (flat disk) as a model of Earth. LOL
shouldnt the south wind be to the other side?
If you mean the wind in the Southern Hemisphere should go in the opposite direction, no, it shouldn't, as the whole Earth rotates in the same direction, towards the East. The Coriolis Effect and jet streams work the same North and South. There is a difference, though, regarding the deviation of the currents of air from the Equator to the Poles, and that's why hurricanes, cyclones, turn counterclockwise in the North Hemisphere and clockwise in the Southern Hemisphere. Water in a bathtub or toilet can do it too, but it is too small a quantity as to be affected consistently.
Flat Earth who?
Very well done, love your videos
Thank you so much 😊
Ok
From a pilot - Well done :) FYI, we use winds aloft data to pick the best flight altitude - for max ground speed, and minimum fuel burn. Ex - Report near Denver - 18,000 feet - wind from 220 at 55 knots 24,000 feet - 230 at 76 knots 30,000 feet - 275 at 98 knots

@@troy3456789 Thank goodness for noise cancellation headsets :)....especially when teaching in or flying light training piston aircraft.
@MarcPagan this might be a stupid question, but as a pilot, can you ‘feel’ the difference?
@@accidentinstrument Feel the dif in wind speeds and direction? If that's the question - No, but wind's impact on ground speed and required course correction are evident.
I will guess its like the gulf stream but happens in the air.
Waitaminute. "Air warmed at the equator rises, it moves toward the poles." I think that one warranted a lot more explanation -- it implies that the north pole is "up", and that's why the warm air moves there. The only hint you left that suggests that's not what's actually happening is that you clarified that the air only moves "up" in the northern hemisphere. I'm actually not 100% sure of the actual mechanism. I *think* it's that warm air, high energy air tends to expand to evenly distribute that energy into cooler, lower energy air (thus, the warm air at the equator moves toward the poles). Right?
The idea that heat goes up is a misconception. Heat travels to less heated areas whether it's up or down. This can be demonstrated by putting a warm bowl of soup in your lap. The heat will go down. This is called convection. When you have a large volume of heated air gravity will play a role. Gas compress when cooled and expanded when heated. So not only can warm ground air transfer it's heat upward to cooler air the heated air itself will move. This is because the same volume of air contains less air molecules than an equal volume of cooler air. Gravity will cause the heavier air to move down which will push the less dense, i.e. warmer, air upwards. This is generally why people think heat rises and is also how hot air balloons. Bonus fact: when you include the different speeds the air moves you get the cause of all the weather in the world. When you include the vapor pressure, the capability of warmer air to hold more water, and land formations like mountains you get everything you need for all the weather on the entire planet.
@user-ln1ec9qr5y heat from the bowl of soup into your lap is conduction rather than convection I think
@@accidentinstrument yes, you are correct. I was trying to dispel the myth that heat rises.
