Then I will modify the picture to the necessory abstraction. 0059ご冗談でしょう?名無しさん2022/02/03(木) 01:43:20.68ID:51hPRa3R>>58 これにファインマンはこう答える。 I'm sorry I can't do that for you.I don'tknow how. I have no picture of this electromagnetic field that is in any sense accurate. I have known about the electromagneticfield a long time -I was in the same position 25 years ago that you are now, and I have 25 years more of experience thinking about these wiggling waves . Wen I start describing the magnetic field moving through space. I speak of the E- and B-fields and wave imagine that I can see them . I 'll tell you what I see , I see some kind of vague shadowly , wiggling lines -here are and there is an E and B written on them somehow and perhaps some of the lines have arrow on them an arrow here or there which disappears when I look too closely at it. When I talk about the fields swishing through space.
