The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Simple Machines Made Simple,’ which raised more than seven times its target on Kickstarter, wants to demystify mechanical engineering for kids. How do you explain the laws of physics to a toddler?

[Tim] noticed recently that a large number of projects recreating discrete logic tend to do so with technology around 70 years old like resistor-transistor logic (RTL) or diode-transistor logic (DTL).

Billionaire tech titan Bill Gates said his father stuck to the "love and logic" parenting concept, one which worked so effectively he wanted to pass it on when parenting his own three children.

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
