Andrew Beal Offers $1 Million To Solve His Math Problem, Beal Conjecture Remains Unsolved Since 1980s. A Texas banker with a knack for numbers has offered $1 million for whoever can solve a complex math equation that has stumped mathematicians since the 1980s.
First of all, the top loading balances are less precise by a factor of 10 and secondly, air currents around the pan can reduce that precision by as much as another factor of 3 or 4. But the top loading balance is the instrument of choice where precision is not of great importance. Here is one our top loading balances.
The front beam reads continuously up to 10 grams, and the middle beam always reads in 100-gram increments. The far beam is responsible for measuring in 10-gram increments, and each weight must be placed in its appropriate groove. It is important when using a triple beam balance to always take two readings for the most accurate weight possible. If using a container to hold the material to be measured, measure the container first, and then add the material. Learn more about Chem Lab.
