Cecilia Payne
Cecilia Payne and the Composition of the Stars Cecilia Payne (1900–1979) Payne began a long project to measure the absorption lines in stellar spectra She showed that the wide variation in stellar spectra is due mainly to the different ionization states of the atoms and hence different surface temperatures of the stars, not the different […]
MinutePhysics
Our new favorite site and Youtube channel: MinutePhysics Today, so far, we’ve watched all the following videos. She’s now playing Minecraft, and I get to sit back and wait until she starts regurgitating what we’ve just watched. This is one of the most enjoyable aspects of educating her as we do – being present when, after […]
Our Unseen World
This is a new series we are watching on Netflix The Electromagnetic Spectrum The heat produced by the Sun travels from the Sun to the Earth via waves known as electromagnetic waves. These waves can vary greatly in their wavelength. Have you ever thrown a rock into a lake? What happens when you throw a […]
Circuitry, Electrons, Atoms, and Catfish
A post under development – as we work through her Tinkercrate (Circuits) this week: Today we read through the Tinkerzine, learning about the basics of electrons, the concepts of particles within an atom, the structure and concept of an atom, how electrons behave, the difference between a particle, an atom, and a molecule, and discovered […]
A Googol & A Light Year – That's How Big
Yesterday and today… We’ve been playing with the abacus, learning about the Orders of Magnitude (what we call each major transition in numbers, as they increase exponentially), and multiplication via sets thanks to a few beads on sticks. Yesterday, we talked about how, with each added zero, we increase the size/amount of the number. She’s […]
