AI Thread Summary
Invisibility cloaks utilize advanced materials to manipulate light, allowing objects to become less visible or seemingly disappear. These cloaks often rely on metamaterials, which can bend light around an object, creating the illusion of invisibility. The discussion emphasizes the importance of understanding the basic principles of optics and light manipulation without delving into overly complex scientific jargon. Simplified explanations can help in grasping how these technologies function, making them accessible for educational purposes. Overall, invisibility cloaks represent a fascinating intersection of physics and engineering.

Invisibilty cloaks ?

Hey i have a school homework which is : to do a presentation about

HOW do Invisibility Cloaks work ??

OFC i searched on the net but all what i found is VERY VERY complicated explanations !
so please i want a detailed explintations and at the same time not to be very complicated ( SIMPLE)


thank you

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
