-4 to +1°C. Light clouds. No ride, 40′ on turbo.

Drive to work. It’s far too icy after last night’s fog dropped to the ground in the early hours. Then it froze. Traffic was thick which meant an average road speed of 12 mph. That is crap, if I did a speed like that on the bike, I’d be ashamed of myself and would keep quiet about it.

The car wasn’t entirely happy about today either. When I start it, the radiator fan runs on full even with ambient temperature at -5°. Does that mean a temperature sensor has failed?

My moment of maths glory today. A guy at work showed software that draws graphs and he placed a circle on the origin with X^2+y^2=4. His question was how to double the radius of the circle. And, it was me that got it out of all the staff. Then, warming to the subject, I got the expression that moved the circle along the x axis too. My moment of glory you must admit.
