Today i started watching this introductory course in physics. It's a UC Berkeley course given by Richard Muller. He explains physics without using many equations. In this particular lecture he comments quite a bit on 9/11 related physics and dwells on terrorist shoe bombs. He advises the government in such matters, so his views seem a bit politically colored. But he really knows how to present laws of physics in a very understandable and close-to-life manner. I've learned quite some new things from watching this lecture.

Summary of topics lectured about:
- Calories of food
- Peripheral vision of the eyes detect especially motion
- Solar technology
- Tilt of the earth & the seasons
- Global warming in relation to the forming of clouds. When the climate heats up, more clouds may form and may counter the greenhouse effect.
- Canada is 2nd in the world after Saudi Arabia for its oil reserves, but Canada has it stored in oil sand and it's more expensive
- Natural gas & shale gas in comparison to oil
- Coal reserves: The USA has most reserves, then comes Russia and then China, Australia and India. These reserves are big in terms of energy compared to the world's oil reserves.
- Coal and methane can turned into gasoline, but it's still risky in case the oil prices are lowered.
- In politics, there's conflict between the issues of global warming and energy security.
- Coal is the cheapest form of energy.
- IPCC errors
- Sequestering CO2 and making clean use of coal
- CCS = Carbon Capture & Storage

Topics in this video:
- Size of atoms
- Density of atoms
- What makes atoms move, what gives them the kinetic energy?
- Temperature = how much energy do things have
- Thermometers
- Scales of Celcius, Fahrenheit
- Liquid nitrogen experiments
- There are ca 1000 x more molecules in a fluid than in a gas of the same substance per volume
- Temperature of absolute zero on the Kelvin scale means there is no energy
- In the Kelvin scale the amount of energy is proportional to the temperature
- A fire extinguisher has liquid CO2
- Your subjective temperature measurement
- Hot air rises because it's less dense
- Conduction, convection, radiation
