Solution: 1.) R=c*d/(c+d) 2.) a*b=R²

Bag I was able to screen print at a stand at the celebration of "100 Jahre Dortmunder U".

Die Pilze sind dieses Jahr wieder zurück gekommen!

The classic construction with only compass and lineal is impossible. But if you allow one extra angle of arccos(sqrt(π)/2)≈27,597°, then you can square any circle. The area of this circle and square are both π! This property holds true under uniform scaling and is valid for any radius of the circle.

Mushrooms seen on my way home. There was a large three beside them in the past, which was removed. I think remains of the large roots are still in the ground and are broken down by the mycelia.

Small snail I found resting on a leaf in sunshine after light rain.

This cap will be very warm!

I have just learned how to knit socks. This is the first sock I ever made!

The proof can be done in one line, if you use “a=e^ln(a)”, “log_c(a)=ln(a)/ln(c)”, and “(x^y)^z=x^(y*z)”.

I visited the beach of Boltenhagen. Here some impression pictures.

I worked a long time on a gift for my mother, which she could use to keep her shoulders warm.

It has the length dimensions \(\{\sqrt[3]{2}m,1m,\frac{1}{\sqrt[3]{2}}m\}\) and a volume of 1m³. The ratios of the sides ordered by length stay the same after an even splitting of the longest side.

Another version of the previous carry-all.
