content: Wow. This is the most visually easily digestible explanation of trigonometry I’ve seen yet.You DO realise that this video incorporates a CRUCIAL aspect of forming learning patterns in the brain, which, with all our assumed “cleverness” and ridiculously unnecessary polished graphics and HD this and that, has been all but forgotten (or never even grasped in the first place!!)I’m talking about motion synaesthesia - the induction of sounds into the “minds ear” which many people find causes them to “hear motion” in repetitions of movement, especially cyclic patterns. Well this video plays sound effects which synchronise exactly with the motion and phase of the objects - another example of this animation.In the 60s-80s ish, SO MANY educational animations synchronised audible sound effects with visual movement and process. Look at old BBC and ITV for schools programmes - also Sesame Street, etc - movement and sound were created together to fully illustrate the concept of what was happening.As an example, in “Silicon Run”, the series about how processors are made, there are rhythmic, repeating “beep beep beep” and “pop pop pop pop” noises made, one per animation or process, which causes the brain to associate said action with said sound.Animation of a technical subject NEEDS SOUND EFFECTS, and not stupid background music.SO MANY “teachers” are awful ones, should possibly have pursued other careers, and fail at explaining so elegantly.

content: Speak for yourself — I find both background musicandmost sound effects to be annoying and/or distracting.

content: Shhhh..I used those 'slushing / moving' sound effects, to increase CAT PLAY drama, while shaking flashlight / laser pointer in tempo. That 'light' approaching, got louder and louder, until, finally, rushing straight past the 2 playful cats, while they struggled to pounce. All, or most of that was artificial; just lights and sound (effects).Cats find the motion, increasing in tension and tempo is almost ALL conveyed by the sounds, I made " sshhhhuuuusshhhhh...FSSSH"...and they find that 'prey escaping' noise to be irresistible!

content: Quote from: eti on November 23, 2022, 12:35:48 amI didn’t say they were gratuitous or nonsensical. I said that I still consider them to be distracting and/or annoying. It’s not my lack of “understanding”, I’m just telling you that not everyone is helped by sounds. I’m not even saying that Ineverfind them helpful. But I don’t in most cases, including that one.
