It takes 2 neurons to ride a bike
In this weekβs paper, Matthew Cook asks how a computer can control a bicycle without solving the full nonlinear equations of motion, or spending an inordinate amount of time learning through reinforcement learning. Humans seem to learn in a different way: not by deriving equations, and not by crashing thousands of times.
Cook presents a two-neuron network that can ride a simulated bicycle in a desired direction.
Good morning

Most people have no idea this procedure exists - and it can be the difference between life and death after childbirth. This is a detailed anatomical illustration of Manual Removal of the Placenta a critical obstetric procedure performed when the placenta fails to deliver naturally after birth (a condition called retained placenta).
Here's what you're looking at:
A gloved hand inserted into the uterine cavity
The placenta being carefully separated from the uterine wall
The layered anatomy of the abdomen, uterus, and surrounding structures
* The clamped umbilical cord visible at the lower left
A cross-sectional view showing the spine, bowel, and pelvic floor
If left untreated, a retained placenta can cause life-threatening hemorrhage within hours. This procedure, when done correctly, is life-saving.
Medical illustrators make the invisible visible - and that knowledge saves lives.
