How do insects fly? | Sci Guide (Ep 25) | Head Squeeze

[@No0bish1]

i dont understand why you people keep complaining about their asking you to subscribe if you want to see more. They're not holding a gun to your head. youre free to do as you please. just because you dont want to subscribe doesnt mean someone else wont want to either.

[@Nilguiri]

If you increase lift on the advancing blade in your anticlockwise rotating example, it will not roll to the left but instead pitch the nose up due to gyroscopic precession.

[@psalmpson]

This was the most epic headsqueeze video ive ever seen, simply because of the background music

[@SWatchik]

Just proves the answer to anything can be found in nature.

[@slopebomber]

You forgot to mention the vortex coming off the back of the stalling wing.

[@Riddick0163]

The helicopter part is a bit off. Speed doesnt stall an aerofoil, the angle of attack (AoA) does (generally around 16° on an unmodified aerofoil) The advancing blade will actually reduce its AoA to compensate for the retreating blades loss in air speed, keeping the overall lift envelope centered over the middle of the rotor disc. What you are suggesting is producing more lift on the advancing blade (your right), which would cause a roll to the left.

[@ProfAwesomeO]

actually sweaty, having wings doesn't automatically grant you the ability to fly. This video is disguising how some insects move their wings to allow them to fly witch is really quite interesting. I recommend you actually watch it.

[@Nebucatnetzer]

Richard Hammond did a wonderful documentation about this, with some really beautiful high speed shots.

[@_chipchip]

I think the internet is pretty cool.

[@Nilguiri]

Yes, gyroscopic precession seems counter intuitive at first to people who are not familiar with it. Cheers.

[@TheFounderUtopia]

One would think that pushing the flat of a wing upwards very quickly would produce a powerful downward force rather than lift, how very counter-intuitive.

[@silentwf]

I like how the bee is modeled as a fur ball!! Haha

[@MrKennichu]

Very Interesting!

[@Zuraneve]

I've gone through maybe 175-200 of their videos in the past 4 days. Oddly, the constant asking to subscribe hasn't gotten on my nerves yet. (Normally this sort of this would irritate me to no end by now.)

[@IstasPumaNevada]

Asking to subscribe at the end of the video would be a lot less annoying, especially to everyone who already has.

[@Taino21]

I like this new guy. But some words I couldn't hear very well. But otherwise great video and interesting topic. He kind of reminds me of a younger James May. Sort of :-)

[@nickrich56]

... dragonflies ... butterflies ... moths ... these guys all use their wings differently than bees ... more secrets?

[@siyacer]

Nice

[@Slarti]

I think it is considered impolite to constantly suggest subscribing, just think what it would be like if every youtuber in every video they created suggested viewers subscribe. It's the equivalent of the spam email - I develop software and would never email my users suggesting they download the most recent version, those developers who do soon become unpopular and for a good reason too.

[@aaryatodankar4949]

Does Bernoullis principle not apply to insects??

[@metou3072]

I agree with raging Celt. There is an active campaign to suppress knowledge in the world today. Flying insects have dielectric (does not react with electricity/magnetism ...its neutral) Pockets inside their wings that gives them the ability to levitate. What this man is talking about it's how they move in a direction when they are levitating. They flap their wings until the frequency matches its surroundings. You can think of it like an air hockey table except they use magnetism or more accurately the dielectric properties of their wings.. instead of air and what this does is reduce friction. On an air hockey table the air reduces the friction between the table and the puck allowing it to move easier. It is magnetism of the charged particles that makes up everything in the universe that is the reason for the friction. flying insects can get around that by flapping their wings at the frequency of their surroundings which reduces friction so they are able to use the magnetism ..more accurately lack of magnetism reacting with the insect.. around the insect..its like a halo around the insect and they use their wings just for the direction.. This is why insects can change direction instantly. Insects would not be able to fly if they had to deal with the magnetism of the charged particles in light and molecules that make up the atmosphere. there would be too much resistance

[@beriligum]

Interesting, although as I watched the video rather early relative to its upload there was no annotation on your face to subscribe, which looked slightly odd.

[@salvab13]

why is everyone complaining about been asked to subscribe? i did not even noticed it. stop been so butthurt people

[@qaibthai8996]

the flaps that flies make come close to the flaps i made while watching her. lol

[@mathjb94]

So bees swim in the air? Cool!

[@TheMangasm]

So a Bee is essentially a flying kayak?

[@projecta3halkida]

no,there is a percentage of the lungs which is situated in the low and it's called dead space because there is no exchange between oxygen and carbon dioxide

[@MadaxeMunkeee]

This video was interesting enough, but I felt like the talking and jump cuts were a bit slow? People on youtube usually talk really fast though, so I guess I might just be used to that. Also some more variation in tone, and more expressive style way of talking would help I think.

[@Riddick0163]

Yes i am aware of that, but due to KZbins awesome character limit, i couldnt fit in explaining gyroscopic precession. And im sure if i said a force on your right would cause nose up pitching moment would confuse people more haha. On second look, i should have just left it as a force on your right.

[@apersonyoudontknow3346]

0:50 Wait is that why enthopters have horrible stability

[@Kill0Zapper]

What's on your right ear?

[@Tupster]

If it really bothers you go ahead and unsubscribe. I'd rather not see the complaints.

[@JordanGough97]

Fellow pilot approves this comment.

[@SMOshee]

I have to listen to that again! lol

[@hellsjester31]

2:50 What?! How on earth can a faster relative airspeed result in a rotorblade beginning to stall? Even if you increases the angle of attack (which would be stupid due to dissymmetry of lift in a helicopter).

[@projecta3halkida]

no, there is a percentage of the lungs which is situated in the love

[@danielbloch7941]

I did not understand the benifit of a stall

[@cassrobinparker9065]

They use their wings.

[@gadgetwhore2]

penguins has wings.

[@UpsideDownMon]

why wouldn't a plane fly if it was the size of a bug?

[@madmaxdylan]

hey just wanted to ask a question, maybe you could do a video on it... "Are our lungs 100% efficient at getting Carbon Dioxide out of our body?"

[@jamesvincent1567]

No because it uses Diffusion

[@madmaxdylan]

Expound on this please

[@jamesvincent1567]

@@madmaxdylan so say you have two rooms one full of air(100kg) and one with no air and then you let them mix the air will mix equally so both would have 50kg

[@madmaxdylan]

@@jamesvincent1567 I understand that but don't see the correlation with our lungs

[@Balidor]

Insects fly just like we swim ;)

[@TMIGT]

am i watching a robot presenting? lol

[@RyanNoseBest]

2:41 did he just say that helicopters have wings... -_-

[@RockNLoad07]

Why would a plane the size of a bee not be able to fly??!?!??!

[@Scotts-Thoughts]

pretty sure what he was getting at was that if a plane was the same proportionate size. It wouldn't fly. The wings of an airplane must be a certain size in relation to the rest of the plane in order to create enough lift. In the instance of a bee it needs the reverse wing flap in order to keep it airborne... much like "treading water" keeps you afloat in water, so does the flapping of bee's wings enable it to fly.

[@HoxTop]

Hello

[@101spacecase]

seems like common sense at work

[@crashtest2302]

I don't believe that's how helicopters work, if you look at the blades on the rotor, they look like small airplane wings, causing a high pressure system under the blades, causing lift.

[@vvatto]

Who knew!

[@lauriespafford]

Ask for subscribe at the end not in the middle

[@Billaboi88]

Im normally not negative, but he really was a bit dull, he needs to take a deep breath and think about how he can engage the camera a bit more fluidly and not be so stiff.

[@AlmightyDoubleHelix]

Many insects hold weapons grade secrets.

[@madmaxdylan]

ok, thanks. why is that?

[@baggins3685]

I can do that.

[@Arcterion]

Anyone else find it rather obnoxious when they ask people to subscribe half-way through the video? It just comes off as desperate. :/

[@Taarnafeather]

I really liked this one, but pleeeease... Stop Asking Us to Subscribe! I mean, really... Just leave the button anywhere in the video, but stop asking... Not cool. This is internet and it is not cool.

[@EnderGaming001]

HAHAHAHAH, GET IT? HOW DO INSECTS FFFFFFFFFLLLLLLLLYYYYYYYYYYYYYYY? GET IT? FLY? BECAUSE IT IS AN INSECT HAHAHAHAHHAHA

if they ask for one more subscribe, i'll unsubscribe and instead visit their channel once in a while

#illuminati

I'm sorry, but this person is not at all engaging. He makes the video very boring. Please, if you're going to make an educational video that is supposed to appeal to the viewer, then do it with more energy! Don't make a monotone monologue....xDD Cheers!

Well someone has no sense of humour ;)

Okay drug dealer

Please stop telling us to subscribe, especially in such annoying ways.
