Some days ago I bought a new pair of sneakers. I tried them after work today at the gym. I didn't run any faster. My endurance wasn't any better.
I was very disappointed.
Money can't buy me running ability, and happiness? Tomorow I will go back to the store to complain.
After my exercise, I went to the university to attend a guest lecture on astrophysics and cosmology.
The lecture was in the big auditorium where I took my undergrad courses in calculus and complex analysis 25 years ago. Cool to be back.
I learnt that there are some 500 billion planets in our galaxy. Millions of them have conditions similar to the earth.
In the future, Mars will become like the Earth, and the Earth will become like Venus. On Venus the temperature is 400 degrees (Celcius). The longterm weather forecast is not good. But this is still a billion years into the future.
The best things in life are for free; science, knowledge, maybe happiness ... and a couple of other things >;)
