COVID Phasebar phase 1A

Be a Part of the New Astronomy Discovery Center

Opening in Spring 2023, the Astronomy Discovery Center (ADC) at Lowell Observatory will be where curious visitors come to be awed by the cosmos and learn about astronomy. Lowell Observatory’s Deputy Director for Science, Dr. Michael West, has selected quotes and equations from well-known scientists and authors to be included on the ADC. By having your name associated with a famous quote or equation, your gift of $2,000 will support construction of the ADC.

Now is your chance to leave a mark on this new facility and help us open the minds of visitors young and old.

For more information contact Shannon Gonzales at (928) 255-5059 or sgonzales@lowell.edu

Maxwell’s equations. These four equations describe the behavior of electricity and magnetism. They led 19th-century physicist James Clerk Maxwell to conclude that light is an electromagnetic wave that travels through space


The second law of thermodynamics. It states that the amount of entropy (a measure of disorder) in the universe inevitably increases with time. Entropy is sometimes called time’s arrow because it may explain why time only flows in one direction – towards increasing entropy.


The energy of light. Here h is Planck’s constant, c is the speed of light, and λ is the wavelength of the light. Shorter wavelengths of light, like X-rays and ultraviolet, carry more energy.


The Hubble–Lemaître law describes the expansion of the universe. Specifically, it says that the speed (v) with which a galaxy is moving away from us is proportional to its distance (D). Pioneering observations that led to the discovery of this law were made at Lowell Observatory by Vesto Slipher


The Stefan-Boltzmann law shows how a star’s luminosity depends on its radius (R) and temperature (T). The strong dependence on temperature means that a hotter star is much more luminous than a cooler one.


The equation of an ellipse. Kepler’s first law of planetary motion says that the planets follow elliptical orbits around the Sun.


Einstein’s Special Theory of Relativity shows that an object’s mass depends on its speed. The mass becomes infinite as the object approaches the speed of light.


Ludwig Boltzmann’s equation for entropy reveals a deep connection between the microscopic and macroscopic worlds. It shows that atoms are inevitably arranged in increasingly diverse ways as the universe evolves.
