Archimedes

The only way to do great work is to love what you do.

Strive not to be a success, but rather to be of value.

The best revenge is massive success.

The only true wisdom is knowing that you know nothing.

The greatest wealth is health.

The only constant in life is change.

The journey is the reward.

To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.

Any solid lighter than a fluid will, if placed in the fluid, be immersed to such an extent that the weight of the solid will be equal to the weight of the fluid displaced.

The surface of any fluid at rest is the surface of a sphere whose center is the same as that of the Earth.

The area of any segment of a parabola cut off by a straight line is four-thirds of the triangle which has the same base and equal height.

There are no numbers that are too large to be named.

The circumference of a circle is three times the diameter plus a small excess, which is less than one-seventh of the diameter but greater than ten seventy-firsts.

If a body lighter than a fluid be forcibly immersed in it, it will be driven upwards by a force equal to the difference between its weight and the weight of the fluid displaced.

If a solid heavier than a fluid be weighed in the fluid, it will be lighter than its true weight by the weight of the fluid displaced.

Magnitudes are said to be in equilibrium when they are at equal distances from the fulcrum.

If a magnitude be added to one side of a balance, it will incline towards that side.

The center of gravity of any parallelogram is the point in which its diagonals intersect.

The center of gravity of any trapezoid is the point in which the lines joining the midpoints of the parallel sides and the lines joining the midpoints of the non-parallel sides intersect.

The area of a circle is equal to the area of a right-angled triangle whose sides about the right angle are equal to the radius and circumference of the circle respectively.
