"Assume there is no friction" Ah classic

Music is a disaster. Content great.

Why doesn't the research paper link work (I'm trying to reference the paper for my physics project but can't seem to get the full research paper by Dr. Siano anywhere on the internet 😢)

Thank you, very cool

Now i am even more confused than before. There is nothing in this vid abt practical application or testing and adjusting release points. Video for egg-heads only not for a normal dude just tryna learn how to build and tune a tribuchet in his back yard.

@rabbit on da moon why did you stop making videos? will you ever start again?

JUST BRILLIANT ♥♥🏆🏆

1 2 buckel my shoe

Your losing me...

This is boring as fuck...you might have some good Information...but I've committed loss of interest...use a working model...drawings are rubbish and Not that good to interperate to working

friend if this quantum lock be invention? (false). The nitrogen freezed Aether nearest magnetic poles inside material...think in this (the material now is magnetic ) AETHER CAN BE PROVED (true). {isso explica porque o imã pode girar em seu eixo magnético...em supercondutividade isso não deveria ocorrer [variação do campo magnético geraria Ed corrent (fomos enganados?)] }. Congratulaitions! like you!

wow so cool ! quick question do you prefer cats or dogs! :D

I love the drawings, and strangely the drawings make it easier to understand

Now, put the trebuchet back on it's wheels like it's supposed to be and explain why it works a LOT better.

Happy vibes! Happy Summer Solstice 📧🎈

Easy nerd, I just need the dimensions

What

Hey very cool!! I just now discovered this happened, 3 years before I built my rotary trebuchet kzbin.info/www/bejne/lXKoc4OnhNGbrqM I was also fascinated with the energy transfer between weight, rotator, sling, and projectile. In my machine the rotator significantly slowed upon unwind and release, indicating energy transfer. It also kept going a bit and often got tangled.

Hey, i need some help understanding the ecuation at 1:36, can anyone help me with it? I read it as: θ=a*tan(1/μ) but have no idea what that (a) means.

NO THEY DON T !!! ELO IS MADE FOR 1V1 LIKE CHESS NOT FREAKING 5V5 GAMES

So, what is the explanation? All I saw was that classical EM cannot explain the effect and it needs a QM approach, but there was no explanation provided, just the usual fluff about BCS theory, accompanied by music.

This all just sounds like a bit from interdemensional cable

Great content, but man, that narration killed everything. Just fast reading material in the most boring way :<

Had to watch this with no sound and captions only. Why don't people understand that educational videos shouldn't have background noise? Is it really that difficult to understand?

I was laying in bed, thinking about trebuchets. Wondering how you “press the trigger”. My search led me here. You answered my question. You also reminded me why I love physics. Thank you for the video.

Despite being unashamedly scruffy, this presentation is helpful to understanding the phenomenon.

Bro bro.. bro, the background music is extremely distracting.

So this mean lol ranking system actualy not accurately measure ur skill?

VERY hard to hear what you're saying with the music.

This a great video but I thought a lightsaber battle was happening bc of the music

Since many electron pairs can be in the lowest energy state at the same time, the energy in all the electrons is lower than required to interact with the positive ions therefore, no collisions take place with the positive ions and no energy is lost as heat. The result is zero resistance. This is to the best of my understanding. Can somebody correct me?

How many times you try to make good trebuchet ?

The explanation starts here @ 3:44

Thank you

How far can this shoot a bean bag (need one to go 25 feet using a bean bag for a science project).

This helped a ton with my science project. AWESOME!!!!!!

wow, this is incredibly helpful! It definitely helped me with a physics project of mine. I learned a lot, thanks!

Great physics and video. Narration, not so much. Please speak more loudly. And thanks!

So you explained how electrons act as composite bosons, but how does that lead to the meissner effect. What about a BEC leads to the surface currents which expel external magnetic fields

I think pedagogically you could do this even better. Music off, of course. But when approaching a phenomenon, one should observe the phenomenon only, not the interpretation. Therefore, switch off the magnetic field lines when demonstrating, we want to see only what happens, not your personal interpretation. It is like you give the impression that the field lines are observable. To avoid, you may show the phenomenon in reality instead of on pictures. Now, a question: Is it not true that the only explanation for Meissner effect is what is contained in London equations? To me, the London equations are just descriptions. Therefore, I claim there is no explanation of Meissner effect. Do you agree?

This is a nice video with plenty of mathematics to explain the results. But there's one issue: you're assuming everyone uses the ELO rating the same. They do not. This is evident in smite. People noticed playing ranked (where you can actually see each player's ratings) that the system regularly put people at the lowest ranks against opponents with the highest rank. Worse yet, the rank of the players within each time varied widely. You could see games where one gold player would be thrown into a match with 4 bronze allies, and all gold and silver opponents. Its clear that the system wasn't matching players up based on skill. And you know what? Hi-rez confessed to this. Their system does NOT pair you up with allies and opponents of the same rank as you. In reality, the system is designed to keep your winrate at 50%. If you go above that, the system will pair you up with increasingly bad allies and give you opponents that are increasingly higher rank than you. However, you to start to fall below 50%, then the system gives you allies that are higher rank than you, and opponents that are below you. They claim to did this to boost player confidence, because it ensures that everyone has a winrate of 50% regardless of their actual skill. And they reported that the system was working EXACTLY as they intended; everyone's winrate hovered around 50%, with even the best players not managing to get above 55%. This kind of system creates a whole host of problems that you could write an essay about. 1. Games are ALWAYS one-sided. Playing smite for years, I only ever got TWO games that were actually a fair fight (and I remember them because they were so fair, which was unusual for the game). Every game is made to be one-sided to keep everyone's win rates at 50% 2. Keeping everyone's winrate at 50% makes everyone believe they know exactly what they're doing, regardless of whether they do or not. This results in a culture of arrogance, where everyone believes they're a pro, and because the system often pairs you with allies that are below you in ranking, it IS 100% true that if you lose a match, chances are it wasn't directly your fault, but who were you paired with. 3. Since everyone thinks they know what they're doing, the overall skill level is low. This can really be seen in the different versions of Smite. PC players were clearly better than ps4 players (on average, anyway). However, even on ps4 everyone was convinced that they knew what they were doing because their winrate was 50%, and even if they moved over to pc and got owned hard game after game, their winrate would still be 50%. 4. The 'rewards' are completely backwards. The game literally punishes you if you win, and rewards you if you lose. I actually started intentionally feeding for a while in smite. And you know what? My winrate didn't go down one bit! In fact, I had far more pleasant games when I deliberately tried to sabotage the game than I did when I actually made an effort. I didn't know this at the time, but what was happening was that the system was putting me in teams that could win despite my behavior because I was doing so poorly. So yeah, I got rewarded for intentionally feeding, and punished for actually trying. Wtf? 5. Rigged games. Who enjoys that? Your own skill in such a system literally means NOTHING, because every game you play is rigged to either make you win or lose, depending on what would keep your winrate at 50%. All these reasons (and the fact that the game is COMPLETELY un-moderated, and admittedly so, oh and the game seemed to have NO concept of balance, because the developers claim that even they couldn't play their own game, seriously) is why I left. More recently though, I've heard that dota 2 literally does the exact same thing! If this is true, then how common is it? I always thought it was unique to Smite and its obviously inept development team, but if dota 2 does it also, who knows who else? I don't know if LoL does this (haven't played it in years), but I don't recall the matchmaking system feeling like I was always playing one-sided games. Then again, I did seem to alternate back and forth between winning and losing streaks for some reason; I would literally win 4-5 games in a row, then lose 4-5 games in a row back and forth. How common is this? And we clearly shouldn't be trusting corporations, that are just trying to milk people out of as much money as possible, to make games that are enjoyable and fair. We don't know what's going on behind the scenes, we don't know how the matchmaking or how some aspects of the game actually work. As for dota, there is evidence to back this up. The top players of dota 1 can never get a winrate of over 55% in dota 2, no matter what. It does seem like the system is pairing them up with bad allies to try and keep their winrate down. Even miracle and other top dota 2 players have released videos where they're carrying teams that are clearly far worse than they are. So it IS perfectly possible that this IS the case in dota 2. You don't see this one-sided nonsense in dota 1, though in dota 1, new players are virtually non-existent. As a consequence, the entire player base is made up of people who have been playing a long long time, thus there isn't much variation in skill level. Long story short: just because a game has a ranking system, doesn't mean that its fair. They may not be matching you up in the way that you think they are.

Good stuff and well presented! All the fine folks with “suggestions” in the comments are free to make their own, better, video (not).

Great video! I use it with my physics classes. Videos are hard to follow, very grainy. It would be great if you would redo it using most recent generation iPhone or Samsung S10 or S10+ with super slo-mo.

This video is almost 10 years old, congratulations

Hello everyone that is building a trebuchet for their project, I am too. Good luck!

Bad handwriting and me too

Clove hitch? Lashings? It is an honor to be here my fellow scout.

Rabbit on Da Moon - Do you ever teach in a class room? If you do, do you switch on a music player before you start talking? Like you, I like Beethoven, but honestly, I would have taken in a lot more of the subject without the distraction of the music.

Could you plz tell me the formula for superconductor to produce flux ???? And another question Is superconductor and electromagnet get replel ??????????

You better not have any problems in your life... You smart. Great Video!
