2/2 物理学入門 演習問題 第6回 1. (a) 減衰振動の運動方程式 d²x dx m +ym dt2 dt -at の解がx(t) = Ae™“ cos (at + 8 ) となるためには、α, y, w。 のどのような関数になら -+kx=0 なければならないか示せ。ただし、ω=√k/m はばねの振動数である。 (b) 初期条件x(0)=x,0(0) = v を満たすような解はどのようになるか示せ。その際は x(t) = Aeat cos (wt+8) = Ae-at (cos wt cosdsin wt sin δ) となることを用いて、 A,8 を消去せよ。 (c) 減衰振動の場合、ばねのエネルギー=mu²+=kx2は「常に」単調減少すること をニュートンの方程式から直接示せ。 2 2. 下図のように2つの粒子が3つのバネにつながっている場合を考える。粒子は1次 元の空間しか動かないものとし、それぞれの粒子の平衡位置 (自然長)からのずれを X1X2 とすると、全体のバネの位置エネルギーは V(x1,x2)===kx²+/=/k'(x_-x2)+=kx2 2 と書ける。ここでk, k'はバネ係数である。 粒子 1,2の質量は等しくmとする。 (b) 重心座標xG (a) 粒子 1,2 それぞれの運動方程式を書き下せ。 x₁ + x₂ 2 (c) 重心座標と相対座標に関する運動の、それぞれの周期を求めよ。 = -と相対座標x=x-x2 に対する運動方程式を書き下せ。 Free free 00000 X2 elllllllll X1 IC

Radio Host: durlar aind Roger Ali: Radio Host: Roger Ali: Radio Host: Roger Ali: Radio Host: Roger Ali: Roger Ali: Radio Host: Roger Ali: Radio Host: Welcome back. As I mentioned before the break, Roger Ali is with us today to talk about artificial intelligence. Thank you for being here, Dr. Ali. Thank you for having me. I'll be honest with you. When I hear the words "artificial intelligence," the first thing I think of is the character HAL from the movie 2001: A Space Odyssey. ch tud goons bad Radio Host:ome In other words, the search engine draws conclusions about what we're looking for on the Internet. Roger Ali: Sure. Many people remember HAL. In the movie, he's the computer that controls the systems of a spacecraft. He also speaks with the people on the spacecraft. And he's not very happy when the people decide to turn off the computer. In the movie, HAL becomes very dangerous. That's right, but fortunately, artificial intelligence in the real world isn't like HAL. Well, that's good! Can you tell us what is happening in the field of AI? Many interesting things. For example, when we search for something on the Internet, the search results that we see are chosen carefully. The search engine has learned which websites are the most popular, the most reliable, and so on. This prevents us from seeing a lot of websites we're not really interested in. Tosa Right, so it only shows us the information it thinks we want to see, which includes go advertisements as well. We usually see only ads for products that the computer thinks we might want to buy. You said, "It thinks," but is the search engine really thinking? IST That depends on your definition of thinking. The search engine is capable of learning machine learning-and it does have knowledge. Knowledge about the Internet. Are learning and knowledge part of your definition of thinking? They're part of it, but human beings are capable of so much more. We have our senses hearing, smell, sight, touch, taste-and our emotions. We notice a lot about the world, and we use our judgment to make decisions. That's true, and most computer scientists know that we can't replace human beings with computers. We don't intend to make robots for every kind of job, either. That's just not practical.
