British Scientist Quotes
Find out what an odor is - whether it is an emanation and therefore subject to being weighed, or a vibration and therefore capable of being reflected. Odors are becoming more and more important in the worlds of scientific experiments and in medicine - and the need of more knowledge will bring forth more knowledge, as sure as the sun shines.
[Why do animals] undergo in the course of their growth a series of complicated changes, during which they acquire organs which have no function, and which, after remaining visible for a short time, disappear without leaving a trace... The explanation of such facts is obvious. The stage when the tadpole breathes by gills is a repetition of the stage when the ancestors of the frog had not advanced in the scale of development beyond a fish.
Once acclimatized to space living, it is unlikely that man will stop until he has roamed over and colonized most of the sidereal universe, or that even this will be the end. Man will not ultimately be content to be parasitic on the stars but will invade them and organize them for his own purposes.
This foolish idea of shooting at the moon is an example of the absurd length to which vicious specialisation will carry scientists working in thought-tight compartments.... For a projectile entirely to escape the gravitation of the Earth, it needs a velocity of 7 miles a second. The thermal energy of a gramme at this speed is 15180 calories.... The energy of our most violent explosive - nitroglycerine - is less than 1500 calories per grammer. Consequently, even had the explosive nothing to carry, it has only one tenth of the energy to escape the Earth … hence the proposition appears to be basically unsound.
Light, properly so called, is only a narrowly defined part of a far greater phenomenon, that of radiation in general.... The lengths of [visible] light waves fall between close limits; but the rules of wave motion apply to the infinitesimal waves of X-rays on one hand and to the long radio waves on the other.
Science doesn't always go forwards. It's a bit like doing a Rubik's cube. You sometimes have to make more of a mess with a Rubik's cube before you can get it to go right. You build up this picture of what there is and you believe it to be true and you work with this picture and you refine it but sometimes you have to abandon the picture. Sometimes you discover the picture you thought you had, that everybody thought we had, actually turns out to be wrong.
Research is a matter of overcoming obstacles. That's what research is about. There are problems. There are difficulties. It's hard to make sense of a collection of information or whatever. Obstacles are the nature of research. Maybe that's why some people give up. There's always an obstacle. You overcome one to find there's another one.
The existing theories of the interaction of elementary particles and fields are all unsatisfactory in one way or another. The imperfections may well arise from the use of wrong dynamical systems to represent atomic phenomena, i.e., wrong Hamiltonians and wrong interaction energies. It thus becomes a matter of great importance to set up new dynamical systems and see if they will better describe the atomic world.
