Try focusing your energy on a focal point, like a lens.

The best assistant in science is your own mind, not anything else.

It is not the animal itself that is being questioned, but our own vision; you know, our vision always likes to respond favorably to our established views.

When the question is solved, it feels like nothing could be simpler than this. However, when looking for the answer, it is like catching the clouds in the sky.

Many times, it is better to be ignorant. If the mind remains free to investigate and study, people will not stray into some dead-end paths provided by books.

Nothing is more enduring than "absurdity".

Things that we cherish with our own wishes will eventually be tragically destroyed by the claws of reality.

If science is willing to let go of its pretensions and make children feel friendly, if our university camps consider adding live field learning in addition to dead books, if the noose on the syllabus that the bureaucrats are fond of is not If the pioneering spirit of those with ambitions is completely stifled, then natural history will be able to imprint countless beautiful and kind things into the hearts of children!

The original, real things and formulas cannot be controlled.

A small piece of protein that is infused with life, capable of sorrow and joy, is worth far more than the boundless raw material.

The evolution of life is not a gradual process. It does not necessarily have to go from inferior to good, and then from good to best. Evolution is completed in the form of jumps. Sometimes there is progress, and sometimes there is regression. .

We should not regard life as a kind of enjoyment or a kind of suffering, but as an obligation, an obligation that we must do our best as long as the deadline has not arrived.

Absolutely not. Just walk. As long as you walk, strength will naturally arise.

It doesn’t matter whether someone teaches you about learning. The most important thing is whether you have awareness and perseverance.
