but rather hundreds of scholars who contributed to something that we now call the “Cell Theory”. Basically, this explained to the world what we, as living organisms, are made of. This theory was followed by many more revelations about the complexity of life on Earth that changed the entire...
(1) The mechanism of uranium→hydrogen decay chain, as opposed to the prevailing theory of radioactive decay which holds that uranium-238 decays only to stable lead-206, while all other elements lighter than lead-206 (except for 43-technetium) are stable and they are not thought to decay a...

The theory of star-planet coevolution however holds that the sun itself cannot independently generate energy, nor can it independently synthesize elements. On the contrary, the sun-core-operated physical mechanism of energy generation and element synthesis is essentially a sun-planet co-created and ...
This paper presents an account of the nature of stem cells based on the philosophical concept of disposition. It is argued that stem cells can be conceived
A theory, like the theory of evolution, is more than a guess: it's grounded in fact. A hypothesis is an assumption constructed for the sake of testing
If the conditions are different, any changes the scientist observes in a demonstration ( 实证 ) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory ...
