Do not imagine that mathematics is hard and crabbed, and repulsive to common sense. It is merely the etherealization of common sense.
Radio has no future." "X-rays are clearly a hoax". "The aeroplane is scientifically impossible.
Interpretation
What this quote means
This quote emphasizes the tendency to underestimate new technologies and innovations due to a lack of understanding or imagination.
Lord Kelvin's quote reflects the skepticism often encountered in the face of groundbreaking advancements in technology. It highlights how experts, even those with significant knowledge, can dismiss revolutionary ideas by viewing them through the lens of their existing understanding and experiences. This mindset can hinder progress and innovation as it prevents visionaries from pursuing ideas deemed impossible by conventional wisdom.

In science there is only physics; all the rest is stamp collecting.
There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.
Let nobody be afraid of true freedom of thought. Let us be free in thought and criticism; but, with freedom, we are bound to come to the conclusion that science is not antagonistic to religion, but a help to it.
I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.

When the wrong question is being asked, it usually turns out to be because the right question is too difficult. Scientists ask questions they can answer. That is, it is often the case that the operations of a science are not a consequence of the problematic of that science, but that the problematic is induced by the available means.
The universe is very big - there's about 100,000 million galaxies in the universe, so that means an awful lot of stars. And some of them, I'm pretty certain, will have planets where there was life, is life, or maybe will be life. I don't believe we're alone.
We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.
The problem with intelligent-design theory, is not that it is false but that it is not falsifiable. Not being susceptible to contradicting evidence, it is not a testable hypothesis. Hence it is not a scientific but a creedal tenet - a matter of faith, unsuited to a public school's science curriculum.
The best simulator for spacewalking is underwater - it allows full visuals and body movement in 3D. Virtual reality is good, too, and has some advantages, like full Station simulation, not just part. Like all simulators, they have parts that are wrong and misleading: an important thing to remember when preparing for reality.
They [scientists of centuries past] call on God only from the lonely and precarious edge of incomprehension. Where they feel certain about their explanations, however, God gets hardly a mention.
