Cervical Mucus Before Week Period

Many of the discoveries we enjoy today are the result of chance, serendipity is the term applied to a discovery or a lucky and unexpected finding.
I tell if the microwave and safety glass windshields of cars.

The
MICROWAVE

The magnetron is the tube that produces microwave energy. Was an essential element in building the RADAR. Scientists tried to thwart the plans of the Nazi s was an element that contributed decisively to the defense of Britain during World War II.
One day in 1946, a Raytheon engineer Percy Spencer Company, was testing a magnetron tube when he reached into his pocket where he kept a bar of chocolate and found that it had melted into a sticky mess. Spencer knew that the magnetrons generate heat, but he had not noticed any heat. Even so, heat the magnetron could be the cause?
not worried about the stain on his pants, but intrigued by it all. So I sent for a bag of corn kernels near the magnetron put and within minutes got popcorn on the floor of the laboratory. The next morning, arrived at the lab with a dozen fresh eggs. Put one in a container with a hole aligned with the magnetron. A colleague, browsing, came too and found his face splattered egg. Spencer knew immediately that it had been boiled egg inside out and the pressure it had exploded. The question era, ¿por qué no otros alimentos?

CRISTAL DE SEGURIDAD

El descubrimiento del cristal de seguridad fue debido a un accidente. En 1903, un químico llamado Édouard Benedictus subió a una escalera en su laboratorio para buscar unos reactivos en un estante e inadvertida mente hizo caer un frasco de cristal. Oyó cómo se rompía pero, al mirar al suelo, observó cómo los fragmentos continuaban más o menos unidos y mantenían la forma del recipiente.
Al interrogar a un ayudante, Benedictus se enteró que había contenido una solución de nitrato de celulosa, un plástico líquido que se had evaporated and that, apparently, placed inside a thin layer. Since it seemed clean, the assistant had not cleaned and had returned directly to the rack. Benedictus wrote a note, but forgot the incident.
The same week that discovery, a Paris newspaper published an article on the recent spate of car crashes, and when he read that almost all drivers were seriously injured due to the cuts he was inspired: It was 24 hours straight experiencing with layers of liquid crystals which are then applied to break: The next afternoon had produced the first piece of Triplex (safety glass) that appeared full of promise for the future. There were two sheets of glass enclosing a layer of cells between them.
builders cars showed little interest in these crystals, they said the driving safety depended mainly on the driver's hands, not the manufacturer. In fact, had been incorporated security measures to prevent accidents, but not to minimize damage if occurred.
The first application of this crystal was in gas masks. After the car manufacturers consider the success in the battlefield, the main application became, effectively, the windshields of cars.
However, this does not solve all the problems. In case of breakage, contact with the inside of the windshield could cause cuts in the skin. To prevent this, it was decided to add a second layer of plastic on the inside center. In 1987 he settled in some cars on a trial and the results were very promising. In a frontal collision, a woman's head hit the windshield that had this new layer. He suffered a concussion but had no cuts on the face or head.
