Charles Liu is amazing, please bring him on more. He's so gregarious and pleasant while being knowledgeable much like yourself
Yeah his personality is interesting. Slightly hippie like with alot less intoxication. Oh and way more intelligent
@@usern4metak3ns haha yup, that might be a much better description
Much like myself?
👍
I love it when we get both chucks
Chuck needs to adjust the microphone! Sound is clipping!
glad someone else noticed it
He needs a new mic
I am a College Computer Engineering and Mathematics student who is also competing on the VCU Track and Field team. I always loved startalk and the thoughts and journeys of the cosmos, but when you start talking about my sport thats when I have to step in lol. I love you guys, keep it up.
The "scream" done during sports helps force residual air from the lungs so fresh air can be immediately supplied after the exertion and (more importantly) flex the majority of abdominal muscles so more energy can be applied.
Makes sense to me that one of the oldest forms of human competition would be comprised of pretty "primitive movements" that were used for survival very long ago such as throwing spears(javelins), shotput(rocks), running, wrestling etc. To me it's a cool way to go back in time and feel a little nostalgia to how our ancestors lived.
@14:40, my throwing coach taught us to swear whilst throwing, NOT IN ENGLISH because that would get you disqualified. But you could swear in German, Spanish, Polish all you liked.
It helped compress your core.
As a thrower for shot put and discus i really loved how they explained the physics of throwing
I had to look up Ryan Crouser's throw. That technique is wild
The Olympics are fun to watch. But the science behind it is better 🤓
@Johnny Appleseed what are you talking about?
Yeah like jiggly physics in gymnastics... So sciency.
Mmm
@Johnny Appleseed ahhh yes Ben Shapiro. Btw transgender is supported in the scientific community. I’ll post a link to a study if you want.
@Johnny Appleseed You disregarding a scientists arguments as lies to avoid being cancelled by some shadowy collective, is no diffirent from a flat earther.
Assuming someone is lying about their opinion because it is dirent from yours is disgraceful.
Anyone remember the show 'Sports Science'? That was one of my favorites growing up.
Haha i love your Olimptalk ! Great idea to see crazy science guys talking about competition of people! Greetings from Poland!
Off topic but I just told someone I needed the 4th dimension to make an appointment. I loved every second of it and had to tell you about it!
Hi there, Doc. Tyson! One of so many huge fans here! Are you onto the Mehdi/Mould wager thing? We are dead curious about that!
Charles .. my fav geek 🤓💕
I really love Charles Liu!
enjoyable discussion
Neiland chuck you guys are so awesome! Wish I could spend just 1 night looking up with you guys. Would be the ultimate life experience!
Me too!😄👍
@@riverpenzo885 wonder if it's possible to make happen. Probably cost more for their time then I could afford. I mean he does say he's our personal astrophysicist lol
Charles is really going for the rock star look, love the Herman Li look!
I really liked how when they discussed why airplane wings don't spin, and my immediate thought as a novice aviator and serious av-geek, in essence Helicopters are spinning discs with a counter-balance to allow for directional control (tail rotor). Airplanes can achieve lift with spinning wings (think Osprey V22 or Harrier Jump Jet or the F-35C that have VTOL), wings work better with some horizontal speed then they can go the distance.
Once enough horizontal speed is achieved they do the same basic thing as a disc over a sphere but instead its with the change air pressure above and below the wing surface, and hit a sweet spot at 30,000ft or so because drag is sufficiently reduced to counteract the inherent loss of drag.
Think of it like this: an aircraft at "liftoff" speed (particularly with bent/angled wings like we see on a modern airplane like a A320 or 787) is moving fast enough that the diameter of the disc of pressure extends from the nose to the tail and each wing makes up an equal radius to the center of the cabin when viewed from above (or below), so airplanes are still being much more efficient than a sphere closer to a disc when it comes to lift
(Please note wider wings than a fuselage length allow the lift generated beyond that "disc" of lift to apply greater force without more work similar to how torque works when pushing on a hinged door nearer or further from it's axis of rotation. It's why gliders are short but wide and 747's or A340-600s are about as long as they are wide)
P
Is this video a part of an actual episode of Star Talk or just original 15 minute content?
They recently started to upload cut clips of full episodes because, more views, I guess.
HOLY SMOKES I FORGOT TO GIVE A THUMB UP :O
Luv u Charlz ♥
The spining in hammer throwing is the nost difficult thing about it, you have to get your feet on a specific way and everything is so precise it takes months and months to start to understand the movement
Chuck makes me laugh every episode.
Amazing
I saw Bob Skinner set the world record in Javelin in 1969 (I think). We were sitting on the end of the track facility and it was coming right at us.
I love Geek in Chief!
I liked it better than geekpertise at first.
But after saying it a couple times, both have a ring to them. 😆
I love star talk. It always brings the geek side out in me. How far would the cannon ball go if it was thrown on the moon?
You left out SO many variables. 😆
In archery I'm pretty sure the optimal angle is 42.5° for range. Does that translate to other ballistics in air too?
Holy.... Charles Lui grew his hair long since yesterday.
If you're referring to the video with Zachary Quinto they posted yesterday, that was an old pre-covid recording. However, it's still weird to see that and this now. When he first appeared on this, I was like "whoa!!!"
Charles Liu has quite the hockey flow.
Charles Liu the Geek Master
Regarding Javelins: the center of mass was moved forward in the last 30yrs. 100yrs ago they were nearly 10’ long, as throws became longer they shortened them to their current lengths
You guys are very clever
Well...when I was deployed, we were part of the initial greetings committee. This left us in a desert, and in 2001 mail delivery service was a bit nonexistent. So, during down times we rapidly ran out of things to do that didn't cause somebody to bleed. With the only widely available resources being sand and empty ammo cans, we ended up with the cubed versions of all these throwables, and a flagstaff javelin. They were heavily used daily, until the first care packages started trickling in, and never acknowledged to exist again.
What if we use a solid tube + handle instead of the wire/chain for the hammer throw?
Will it go further since the handle carves through air easier than a dangling wire/chain or will the stationary weight of the tube + handle make it fall faster than the wire/chain because the wire/chain doesn't maintain a specific form during the duration of the throw?
Less stable for the holder.
So a spinning disc travels smoothly through the air for the same reason a bicycle stays upright when it’s moving but falls over when still. The rigidity of a spinning object is more efficient than the wobbling of a non-spinning object.
Now what about the javelin dude threw in Revenge of the Nerds? The super wobbly one? How aerodynamic would that be?
As for throwing stuff, you should look at juggling. There's lots of science and maths involved like siteswap and I believe that club combat juggling sh9uld be an Olympic sport.
As a skill, it's probably easier than the skill of walking and certainly talking but because not everyone learnt it and because most people have been walking since they were very young, it seems much harder to learn.
Chuck Nice is Great!
If you would like a first hand experience of throwing things for sport, your welcome to come axe throwing. Lol I can't get enough of of star talk.
Playing with axes, sounds great
The ideal launch angle for the shot is more like 35-40°, due to limits on human physiology. (You can deliver more energy in the horizontal direction than you can in the vertical.)
Why is this only 15 mins man??? we want the full 3 hours of it!
Everything I learned about the javelin came from Harold Wormser and Lamar Latrelle. Wormser was a master at aerodynamics.
Chuck Nice, please buy a new microphone. The sound is quite hissy.
Neil need to disconnect his chair from the tripod or table holding the camera. he move, everything shakes.
@@Sir.Craze- of all the hosts, Chuck gets the most excited duing the talks so he definitely needs a better mic.
@@etegration he talks with his whole body.
@@Sir.Craze- dont worry. i got your point. maybe my response wasnt clear. sorry.
I always wonder why if the Olympics have a discus throw why not a Frisbee throwing contest?
Heart Charles
Wish they had answered whether Lamar could have actually thrown that javelin so far in "Revenge of the Nerds "
About the guttural cry, I think it relies on the same principle as a doctor telling you it's okay to scream in order to be able to stay still so that he can stitch you up properly. If the pain is released through screaming you won't be moving around trying to hold it in. Similarly, that guttural cry carries with it a release of energy that can indeed carry the object you're throwing further. You can try it in your backyard. Throw an item without screaming and then throwing it again while screaming and compare the distances. You might even notice that your body instinctively wants to scream.
It's all fun and games until your neighbor calls the cops on you. "Yes? 911? There's a maniac who's yelling really loudly and throwing rocks"
@@TangoWolf09 I didn't think about it like that. Probably because I live in a very remote area within a field of chestnut and walnut trees and have only two neighbours close to me.
Chuck is on fire
Neil and Chuck seem to be rather down to Earth kinda guys. I would like to know their views on the shft. What would they do.
Guys you need to do the science and physics of archery, how does the bow string and limbs of the bow store energy, how does the arrow accelerate, how the arrow arcs through the air, the spin of the arrow................because science..........
The flying disc, commonly known as Frisbee is the solid object thrown the furthest from the human body.
my sports teacher would disqualify me when I did a spin with shotput ! I was beating the older kids by a whole meter
I haven't finished watching the video to provide a valuable comment.
Same
Me too
A small comment for the video, a giant statement for the community
The optimal angle for javelin throw is at about 37-38°, without wind, as its trajectory is not a parabola, but a ballistic trajectory. Against the wind, the angle becomes smaller, 34-37° and with the wind, the angle becomes higher, 38-41°. The only throwing discipline with an optimal throwing angle close to 45° is hammer throw.
Correct. Due to air resistance in flight, the optimal release angle is always less than 45º. In a vacuum, the optimal angle would be 45º.
I didn't know I played sports everytime I threw stuff.
StarTalk - sports edition! (reaching for next video button) ... Olympics! (stopped, giving it a chance)
Can you do a explainer on Chucks ceiling fan? Lol
Guys forgot to take gravity into account. I mean, if you have a cannon that reaches the same speed no matter the angle - yes, the farthest angle is 45°. But you usually have the same force, not speed. The higher you elevate the projectile, the more force it takes to achieve the same speed. So, maybe it's goot to throw stuff a ittle more horizontally
Neil, you have some anger, oil man eyebrows.. lol I love you, Neil.
Love me some Liu....NE1....?
45° is certainly true for an idealised object, but you guys just mentioned that the javelins are tip heavy - doesn't that change the trajectory or do something funny that you'd have to compensate for?
It's an aerodynamic effect. The position of the center of mass changes the aerodynamic pitch moment which can mean a different rotation of the javelin in the air and therefore a different optimal angle, but if there's no air it's back to 45 deg regardless of where the center of mass is.
Charles Liu=Like
Love your stuff. Chuck, turn down the gain on your mic.
turn down your volume problem solved
Example of both sides making a negligible issue into a problem.
It was a little garbled at times, but Chuck's comments are hilarious.
Now I've gotta search shot put growls thanks Star Talk 🙄
Did you know competitive art was once an event in the Olympics
Along with things like Music, Poetry, and Town Planning.
when you learn more in star talk than in physics class
You don't learn how to do calculations here.
is the discus also used in warfare back then?
Maybe in household warfare with dinner plates.
About cannonballs ⚫️
I at least was 6or 7 playing in a field where the ozarks
Meet the delta I found a steel ball about the size of a
Baseball where men had been using a back hole 🕳
For a main a six by six square foot dig about six feet down I was safe it was easy getting in an out that is how I found it 🤷♂️ from the inside wall I showed it to my dad the rest is a story I have always been curious about
Present day I know not what became of it. ? 🤔💭 However I do remember my dad had purchased a new Cadillac also we had a great Christmas that year 😁
I’m thinking he did what needed to be done it’s in a museum somewhere?
He passed on so I am not certain however since I have been a late bloomer it probably laid there from our follies of civil war. I’m pretty sure that a great Archeologist figure this one out for me at the time it was a toy to roll around as I played as I was young until my dad discovered what it was. 😁 I never saw it again
True events. Scouts honor

Off topic ... Gravity causes time to go slower or faster because atoms beat slower or faster when gravity is stronger or weaker. Quartz - 32768 Hz slows down if gravity is stronger - the forces are stronger - it changes state more slowly. My random thoughts - it's hard to describe
I'm sorry i posted this on a unrelated topic but im hoping you see this. @Neil Most people say a black hole has so much gravity that not even light can escape. Light can't escape but light isn't effected by gravity because it has no mass, and we have all heard that high gravity bends space. So hear is my thought and question. Light cant escape not because of lights momentum or speed but because space is bending in so much, there there are no paths out. All roads essentially lead in, and all roads in it lead in farther. So like a one way road there are no paths for light to escape from after/on the event horizon. So lights speed is not really a factor in the escape. Is this true?, and if space is affected by gravity does it, itself have mass and a particle with mass associated with it or maybe itself..... I'm not sure how to say this. But space is a medium we know that. Even if there is not a particle could it be that space is physical in some way that we don't think of. Like everyone says space is a fabric, but not really but kind of really but a 3 dimensional one. Also side note Might it be expanding because it expand into nothing, a true vacuum, that no particles exist or are spontaneously created in. IE high concentration to low concentration. A almost perfect vacuum into a perfect vacuum. If this is possible true i've never heard this explained in layman terms.
I would continue at least 12 months on the same subject...
I saw chuck in a commercial
I remember watching an Olympic running event years back where one of the runners was struck in the leg by a discus… Put him down!
Edit I mean Mr Charles Leu. 👌
I just had a fun idea
Please bring Charles Lou, Janna Levin, Chuck Nice, and Garry O'Riley into the same cosmic queries. That would be like my dream.
Jan in a scientific themed bikini?
All that spinning motion, does it has to do with Newton's Gravity ?
2:18-2:36 literally romans definitely did that
What are the physics of the knuckle ball in football? Aka the sport you play with a ball and your feet, not the other one who is played with an egg and your hands
Throwing at an exact 45 degree angle is actually not ideal, because it takes more energy for a human to produce that amount of force vertically, a thrower is better of trying to create more horizontal force by sacrificing those 5 degrees of height
Are more Olympic records broken when the Olympics are near the equator as people and objects weigh less on the equator ?
I once knew someone who said if it didn't have a ball it wasn't a sport. I'm not that restrictive. If the decision is all or almost all objective, it's a sport. Throwing things is a sport, as there's distance to measure. Running? Time. Soccer? There's objectivity in some calls, but very little and there's a score based on scoring goals. On the other hand, figure skating, synchronized swimming, diving, gymnastics? Too subjective. Not sports.
If we throw it into production, then it's fine as sports, too ... .
A resistence of speed..keep on truck the subject..
A guy from the Czech Republic (Jan Zelezny) holds the world record in javelin...has since the 90s. I don't think it's 100m either
The spinning motion is for building up strength and energy. If one want to punch a target harder spin your hand few rounds then throw that punch, you'll see the impact is much bigger than just extend your hand and throw a straight punch. Same with kicks, same with throwing things. Spinning adds power. 😴
Love the movie Gladiator that's about the Olympics. Sort of lol.
So jealous of not only the contents of Charles' head, but of the covering also.
Oln
there have been Olympics before the Modern Olympic attributed to Coubertin. Just not on a huge international level.
Most of the original Olymic events are military skills i.e. javelin throw.
Sometimes I think Neil is on deGrasse 💨
Chuck wants to see hammer throwers in tootwo. I would rather water polo. Difference but the same.
tem
🍋👻🤔💭👌 For now
I think settling for 🤏pinching a lemon seed an measure this is more my speed. 👻😁👍
Sincerely brother Boo 👻
You need to yell to scare away the projectile
