Working with the 555 555 is used for producing a clock (square wave) at a desired frequency. It can be used in various ways like the astable mode‚ monostable mode etc. Here‚ we deal with the astable operation of 555. Astable mode ensures that the 555 is self-triggered & so‚ it acts as a multi-vibrator. Let us look into the working of 555 in astable mode: These are the connections needed to make the 555 chip run in the ‘astable’ mode. The pin numbers are given in circles. Note the

Towards the end of Bernhard Schlink’s best-known novel‚ The Reader‚ the narrator is pondering his future after taking his state exam in law. He has just seen his former lover‚ Hanna Schmitz‚ convicted of war crimes: she had been a concentration camp guard‚ something he hadn’t known when she seduced him as a 15-year-old boy. None of the roles he saw played out in court appeals to him: ‘Prosecution seemed to me as grotesque a simplification as defence‚ and judging was the most grotesque oversimplification

description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric iron must have a design
