Stir the ocean until the tagged atoms are distributed evenly, just as you would add a powdered drink to a glass Carry the glass to the ocean and dump it in. Atoms are, indeed, very “little particles.”Īn astonishing fact illustrates how small and how numerousĪtoms are. Notation, we could write this distance more compactly as 1.43 ×ġ0-10. The radius ofĪn atom of aluminum is 0.000000000143 meters. Scientific notation is also useful for representing very small The number of atoms in a spoonful of water becomes an easy-towrite 5 × 1023. The same rules apply to numbers that are not even Similarly, 10,000, with 4 zeros, would beġ04, and so on. Number of zeros following the 1 in 1,000 is 3, the same as the exponent in scientific notation. Scientific notation uses exponents to express numbers. To accommodate the very large numbers encountered inĬounting atoms and the very small ones needed to measure them,Ĭhemists use the scientific notation system. His “little particles” captures anĮssential fact about atoms. Motion, attracting each other when they are a little distance apart,īut repelling upon being squeezed into one another.Īs usual, Feynman was right. (or the atomic fact, or whatever you wish to call it) that all thingsĪre made of atoms-little particles that move around in perpetual If, in some cataclysm, all of scientific knowledge were to beĭestroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis Much about atoms as anyone in the world, and this is what he said Winner who spent much of his career studying atoms.
