Researchers at the University of Würzburg have succeeded in detecting exceptionally robust electrical transport in a topological insulator. This could lead to new metrological applications. The work ...

Scientists from St Petersburg University and the Kotelnikov Institute of Radioengineering and Electronics of the Russian Academy of Sciences (IRE RAS), together with Professor Leon Chua from the ...

A few weeks ago, I wrote about fixing the VDO windshield washer pump in a vintage European car. As part of that, I quickly stepped through troubleshooting the system to reach the point where I ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as part of ...

Looking at some anecdotal stories as well as some reasonably valid survey data, it seems that STEM-related subjects are getting serious interest from students at all age levels; STEM stands for ...
