Jules-Henri Poincaré

"To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection."                                                               

 

"Science is built up with facts as a house is with stone. But a collection of facts is no more than a heap of stones is a house."                                                                                  

Albert Einstein

 "The whole of science is nothing more than a refinement of everyday thinking."  

 Ivan Pavlov

"Learn the ABC of science before you try to ascend to its summit. Learn, compare, collect all of the facts."                                                                                 

"In the fields of observation, chance favors only the mind that is prepared. There are no such things as applied sciences, only applications of science."                       

 

Benjamin Franklin

"A good conscience is a continual Christmas."
