Cutting off fundamental, curiosity-driven science is like eating the seed corn. We may have a little more to eat next winter, but what will we plant so we and our children will have enough to get through the winters to come?

不得不讲本书作者真的是对后代非常有责任心的…我真的就是做着好玩，没想过能有什么用，不过看来只要我自己觉得好玩就够了，有没有用是后人的事​​

Maxwell wasn’t thinking of radio, radar and television when he first scratched out the fundamental equations of electromagnet-ism; Newton wasn’t dreaming of space flight or communications satellites when he first understood the motion of the Moon; Roentgen wasn’t contemplating medical diagnosis when he investigated a penetrating radiation so mysterious he called it ‘X-rays’; Curie wasn’t thinking of cancer therapy when she painstakingly extracted minute amounts of radium from tons of pitchblende; Fleming wasn’t planning on saving the lives of millions with antibiotics when he noticed a circle free of bacteria around a growth of mould; Watson and Crick weren’t imagining the cure of genetic diseases when they puzzled over the X-ray diffractometry of DNA; Rowland and Molina weren’t planning to implicate CFCs in ozone depletion when they began studying the role of halogens in stratospheric photochemistry.

Basic research is where scientists are free to pursue their curiosity and interrogate Nature, not with any short-term practical end in view, but to seek knowledge for its own sake. Scientists of course have a vested interest in basic research. It’s what they like to do, in many cases why they became scientists in the first place. But it is in society’s interest to support such research. This is how the major discoveries that benefit humanity are largely made.

@Cronopio 这个俺一直在用！竟然没有发现它有 todolist 的功能​​

书里说到假设女王 1860 想造出电视机，并愿意大量投钱的话，那大概是不可能如愿的，因为前置的技术都还没有发明出来。事实上麦克斯韦方程组发现的时候，谁也不知道它能启发电波塔，通讯卫星，电视和雷达的发明。
所以，不能投钱然后指明必须发现什么技术，科学家们做不到，很可能前置技术还没有发现也根本不知要如何发现。我们应当广泛地探索，等待意想不到的结果的出现。
我就想到我读博的这个 funding 支持的 topic 其实跟我现在做的项目一毛钱关系也没有​​跟 funding body 做报告的时候必须要解释我为什么在做这些东西，都是教授帮我扯的谎，说我是在 explore，是意外的发现，是 creative works 所必须的，一大通一大通的。那边买账了。我教授真厉害​​

其实也不需要特别厉害的成就…有些论文里就是一个小小的 idea 就可以启发后人做出更厉害的东西，所以只要能做一点小小的东西就可以了​​

听说麦克斯韦结婚早但是没有孩子。我觉得如果我能做出些厉害成果，我就不在乎我有没有孩子，我的成果就是我的孩子，为啥要生个孩子然后寄希望于孩子能做出什么成就呢，我自己就行。知识造福千秋万代，孩子一百年后就死了，啥也不是。得真的很喜欢小孩子才生。

His unification of electricity, magnetism and light into one coherent mathematical whole is the inspiration for subsequent attempts - some successful, some still in their rudimentary stages […]

我还以为他要说 some successful, some failed！学到了，以后做得不咋成功的项目就说还在 rudimentary stage​​我国处于并将长期处于社会主义 rudimentary stage（什么

If we no longer insist on our notions of how Nature ought to behave, but instead stand before Nature with an open and receptive mind, we find that common sense often doesn’t work. Why not? Because our notions, both hereditary and learned, of how Nature works were forged in the millions of years our ancestors were hunters and gatherers. In this case common sense is a faithless guide because no hunter-gatherer’s life ever depended on understanding time-variable electric and magnetic fields. There were no evolutionary penalties for ignorance of Maxwell’s equations.

no evolutionary penalties for ignorance of Maxwell’s equations 好好笑😆

But what are these time-varying electric and magnetic fields permeating all of space? What do E and B mean? We feel so much more comfortable with the idea of things touching and jiggling, pushing and pulling, rather than ‘fields’ magically moving objects at a distance, or mere mathematical abstractions. But, as Feynman pointed out, our sense that at least in everyday life we can rely on solid, sensible physical contact to explain, say, why the butter knife comes to you when you pick it up, is a misconception. What does it mean to have physical contact? What exactly is happening when you pick up a knife, or push a swing, or make a wave in a waterbed by pressing down on it periodically? When we investigate deeply, we find that there is no physical contact. Instead, the electrical charges on your hand are influencing the electrical charges on the knife or swing or waterbed, and vice versa. Despite everyday experience and common sense, even here, there is only the interaction of electric fields. Nothing is touching anything.

我觉得这个变种没叫 Xi 太可惜了

@zteng 如果
照着人一日所需的量来摄入蛋白粉那是没问题，我就是担心会不会有人把这个当代餐粉来使用，一顿只吃这个​​其实我也不知道过量多少会严重，但我觉得累积效应还是值得担心的？蛋黄吃多了也是会有胆固醇的问题…

@zteng 谢谢你的解答，不过我不认为是对不自然产品的一种迷思，而是说蛋白粉它的蛋白含量更多，达到了 50% 甚至 70%，更容易摄入过量。肉的话差不多是 20% 的蛋白质含量，人肯定吃不下那么多肉的。类似水果里糖的含量高，但人吃不了太多的水果。可是喝果汁或者吃果干的话就容易摄入过量糖。

@civetkikyou 因为那么多蛋白质也需要身体消化的，产生大量人体不需要的代谢物。具体损伤我也不清楚，可以查一查？不过“均衡”肯定是不对的，蛋白粉就是有超量的蛋白。

@civetkikyou 蛋白粉大量的蛋白，营养并不均衡，摄入过多会损伤肝肾。代餐粉倒是可以。

@SWwind 可能是本来想说 72 hrs, 沉思一下加上了一个 business…
