An apparently easy-looking math problem has left internet users scratching their heads. Give it a try to see if you can correctly solve this elementary-level equation.

Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that ...

Computers built with analogue circuits promise huge speed and efficiency gains over ordinary computers, but normally at the ...

But the real puzzle isn’t whether de-skilling exists—it plainly does—but rather what kind of thing it is. Are all forms of de ...

Abstract: This work extends a matrix-based numerical methodology to cover fully canonical generalized Chevyshev (GC) transfer functions by reconfiguring canonical filter topologies into dangling ...

Abstract: Recently, in-memory analog matrix computing (AMC) with nonvolatile resistive memory has been developed for solving matrix problems in one step, e.g., matrix inversion of solving linear ...

The murder of Rita Curran baffled detectives for fifty years. No witnesses. No leads. Just a single cigarette left behind — a clue too small to mean anything in 1971, but revolutionary decades later.

There is no shortage of proposals for how to make child care more affordable in Washington and ease costs on providers. But these ideas require significant public investment, say advocates. One idea ...
