Light and shadow are important in drawing to create depth and dimension
Understanding value, or how lightness or darkness is portrayed, is crucial for creating realistic art
Practice and experimenting with light and shadow can help improve your drawing skills

Faraday's Law shows that a changing magnetic field can create an electric field. This means electricity and magnetism are like partners that can influence each other.
When electric and magnetic fields change together, they can create electromagnetic waves, which is how light travels. It's like a dance between the two fields that lets energy move through space.
In history, scientists like Faraday and Maxwell noticed that light might be connected to electromagnetism. They found evidence that light behaves like an electromagnetic wave, leading to important discoveries about how we understand light and energy.

Shadows can move faster than light due to their nature as absence of light.
The concept of shadows moving faster than light is based on principles of physics and relativity.
This phenomenon does not violate the speed of light limit because shadows carry no energy.

Prism lights were created after the Great Fire of 1889 in Seattle to bring light to underground spaces under sidewalks. They were designed to let natural light into these areas.
There are thousands of prism lights in Seattle, especially in the Pioneer Square area, but many are damaged or replaced by hard materials. This shows how important it is to preserve these historical features.
Prism lights can also be found in other cities like London and New York, dating back to the late 1800s. However, modern building owners often cover them up because it's cheaper than keeping them intact.

Establish a healthy sleep rhythm by getting morning sunshine regularly, even when it's cloudy, to signal your brain it's daytime and improve your sleep quality.
Ensure you're eating enough food and carbohydrates, as hunger can disrupt sleep. Track your caloric intake and consider increasing carbohydrates slowly to optimize your sleep.
Create an optimal sleep environment by avoiding blue light at night, sleeping in darkness, keeping your room cool, and using ear plugs or white noise to reduce disturbances.

Despite challenges like heavy rain, life in the city continues as usual.
Gravitational lensing, as predicted by Einstein, explains phenomena like Einstein's Cross.
An intriguing thought: what if all stars we see are repetitive images of one lonely star?
