Have you heard of: Percy Spencer

Percy Spencer

Well here I am on Wednesday afternoon, it is a cool and overcast afternoon, feels like it is going to rain again. It rained this morning when I dropped Leo off at school and went to my aqua class but it fined up b around 10am.

This week I am asking if you have heard of Percy Spencer, if not you are not alone as I haven’t heard of him till I Googled who invented the microwave oven.

His invention was an accident, that I had heard before, worked for a company named Raytheon, developing microwave radar transmitters during World War II. When one day in 1945, he noticed that a candy bar he had in his pocket was starting to melt. He was not the first to notice this phenomenon, but he was the first to investigate it.

He decided to experiment using food, including popping corn kernels, which became the world’s first microwaved popcorn. In another experiment, an egg was placed in a tea kettle, and the magnetron was placed directly above it. The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe.

Spencer then created the first true microwave oven by attaching a high density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape, allowing for controlled and safe experimentation. He then placed various food items in the box, while observing effects and monitoring temperatures.

The first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about $5,000 US.

After the war he used radar technology developed during the war to invent the microwave oven, it was named the “Radarange” and was first sold in 1946, the company Raytheon later licensed its patents for a home-use microwave oven that was first introduced in 1955, but these units were still too large and expensive for general home use. The bench top microwave oven was first introduced in 1967, and their use has spread into commercial and residential kitchens around the world. In addition to their use in cooking food, types of microwave ovens are used for heating in many industrial processes.

He was born in Maine 18 months later, Spencer’s father died, and his mother soon left him in the care of his aunt and uncle. His uncle then died when Spencer was just seven years old. Spencer subsequently left school to earn money to support himself and his aunt. From the ages of twelve to sixteen, he worked from sunrise to sunset at a spool mill. At 16 he discovered that a local paper mill was soon to begin using electricity, a concept little known in his rural home region, and he accordingly began learning as much as possible about the phenomenon.

So when he applied to work at the mill, he was one of three people hired to install electricity in the plant, despite never having received any formal training or even finishing

school.

At the age of 18, Spencer decided to join the U S Navy, he had become interested in wireless communications, while in the navy, he made himself an expert on radio technology: “I just got hold of a lot of textbooks and taught myself while I was standing watch at night.” he is reported to have said, he then taught himself trigonometry, calculus. Chemistry. Physics and metallurgy among other subjects.

By 1939 Spencer became one of the world’s leading experts in radar tube design.

For his invention, Spencer received no royalties, but he was paid a one-time $2.00 gratuity from Raytheon, the same token payment the company made to all inventors on its payroll at that time for company patents.

Deadly creatures

box jellyfish

I decided to change Tuesday’s post from indestructible creatures to deadly creatures kicking off with the Box Jellyfish. It’s scientific name is,Chironex fleckeri

They are called box jellyfish because their bell at the top of the jellyfish it has four corners, as well as clusters of trailing, stinging tentacles that can stretch more than two metres (6.4 feet). Wow that is long.

Human encounters occur most often when the box jellyfish comes close to shore to breed in estuaries. “That type of water is muddy, so you can’t always see them and they can’t see you,” he added. If you’re in the murky water and brush against one, you can easily be stung.

While box jellyfish are found in warm coastal waters around the world, the lethal varieties are found primarily in the Indo-Pacific region and northern Australia. This includes the Australian box jellyfish, which is considered the most venomous marine animal.

A box jellyfish sting can be unbelievably painful,the venom is designed to paralyse fish, so it immobilises your nerves and affects breathing and movement. A large dose can cause cardiac arrest and death within minutes.

In North Queensland the big box jellyfish are the most common jellyfish seen during ‘stinger season’. It is so venomous it will kill you within two minutes if you receive two metres or more tentacle contact. If a tentacle touches the skin it results in a very painful sting.

So how do you treat a sting, rinse the area with vinegar, carefully pluck visible tentacles with fine tweezers and soak the skin in hot water, use water that’s 43-45c or 110-113f

An ‘immortal’ jellyfish is swarming through the world’s oceans, according to scientists. This jellyfish is able to revert back to a juvenile form once it mates after becoming sexually mature. Marine biologists say the jellyfish numbers are rocketing because they need not die.

Hello Monday and world it is another nice day here in Newie, not too hot nor too cold, went to my aqua class now I am home for a while till the time comes to go get Leo from school. Anyway Monday means it is did you know day, so here are this weeks facts.

When inventor James Hetherington first wore his new invention, the top hat in London in 1797, it caused quite a stir, so much that he was immediately arrested and thrown in jail because he appeared on the public highway wearing upon his head a tall structure of shining lustre and calculated to disturb timid people.

In the 15th century a man was given the title “official uncorker of bottles” by Queen Elizabeth1. A law was passed that stated all bottles found washed up on beaches had to be opened by this man and no one else, in case they contained sensitive military messages. The penalty for anone else opening a bottle was death.

Hello everyone, here we at this lovely Thursday, didn’t do a post yesterday, why you wonder, well I went to my aqua class as usual but I was that tired that at one stage I nearly fell over that said I stuck it out.

After the class I came home and got changed before going and getting fuel for the car and then down to the shops to get a loaf of bread and more crumpets.

Around 1.50pm Jessica rang me to tell me that she didn’t have an afternoon run as all the children she drives got sent home sick, so she was able to get Leo from school, if I could have I would have done a happy dance.

All that said, it is not the reason for no post yesterday, the reason is, I forgot, simple as that…………..

So anyway today is Thursday and that means it is photo day so here is this weeks photo

Hello everyone, what a start to the day, driving Leo to school this morning I misjudge distance and hit something and did this damage to the car. Leo was worried that papa (Tim) would go mad at me and kept telling me it was just an accident and the car can be fixed and not to get upset about it. I took photos and sent them to Tim, who said he is worried about my driving as in 18 months I have had three incidents of misjudgement and yes at times I am also concerned but overall there is not much wrong with my driving.

Tim is now home and checking out the car and the dashcam to see what happened but at least he isn’t angry and has taken the rest of the day off work, I am still upset.

Well I hope everyone is having or had a good weekend as I can say I did. This morning I went to my aqua aerobics and then to the shops to get another packet of Golden Crumpets has to be Golden Crumpets no other brand are as nice, just saying.

Anyway here is this weeks did you know facts.

During WW11 it cost the Allies about £150,000 to kill each enemy soldier

Around 75% of people who play the radio or other music in the car sing along to the music.

A stack of £1 notes stacked one mile high would be worth about £14 million

All the people on earth weigh about 420 million tons

There are around 25,000 people in the world age at least 100 years old
