Years ago, no math education was complete without understanding how to compute a square root. Today, you are probably just ...

\({9}\) is a square number. \(3 \times 3 = 9\) \(3 \times 3\) can also be written as \(3^2\). This is pronounced "\({3}\) squared". \({8}\) is a cube number. The ...

We’re right to be wary of the perils of thin community, like loss of meaning and, attachment to screens. But thick communities have woes too. In 1992, Covington worked as a freelance reporter for The ...

Researchers are one step closer to understanding how some plants survive without nitrogen. Their work could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.

Gann indicators are normally considered to be a lot more about mathematics and less about charts and technicals. However, Gann indicators have been used quite extensively in identifying opportunities ...

Abstract: This paper investigates the application, design, and implementation of the square root unscented Kalman filter (UKF) (SRUKF) for induction motor (IM) sensorless drives. The UKF uses ...

Abstract: Over the last 20-30 years, the extended Kalman filter (EKF) has become the algorithm of choice in numerous nonlinear estimation and machine learning applications. These include estimating ...

Two days after announcing that candidates appearing for JEE Main 2026 would be able to use an onscreen virtual calculator, the National Testing Agency (NTA) has issued a clarification denying it. The ...
