The earliest bicycle was a wooden scooter-like contraption called a celerifere; it was invented about 1790 by Comte Mede de Sivrac of France. In 1816, Baron Karl von Drais de Sauerbrun, of Germany, invented a model with a steering bar attached to the front wheel, which he called a Draisienne. It has two wheels (of the same size), and the rider sat between the two wheels, but there were no pedals; to move, you had to propel the bicycle forward using your feet (a bit like a scooter). He exhibited his bicycle in Paris on April 6, 1818.

Kirkpatrick MacMillan (1812-1878), a blacksmith from Dumfriesshire, Scotland, invented the first bicycle with foot pedals in the 1830 to 1840's, but he never patented it and his idea did not catch on locally.
A French father-and-son team of carriage-makers, Pierre and Ernest Michaux, invented an improved bicycle in the 1860's. Many early bicycles (called velocipedes, meaning "fast foot," or, more descriptively, "bone shakers") had huge front wheels - it was thought that the bigger the wheel, the faster you could go. Early tires were wooden - metal tires were an improvement, and solid rubber tires were added later. A chain with sprockets was added to the bicycle in the 1880's; this was called the "safety bicycle." Air-filled tires were also added in the 1880's. The derailleur gear system was added in the 1970's.

In 1800, Alessandro Volta of Italy built the voltaic pile and discovered the first practical method of generating electricity. Constructed of alternating discs of zinc and copper, with pieces of cardboard soaked in brine between the metals, the voltic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta's voltaic pile was the first battery that produced a reliable, steady current of electricity.
One contemporary of Alessandro Volta was Luigi Galvani, in fact, it was Volta's disagreement with Galvani's theory of galvanic responses (animal tissue contained a form of electricity) that led Volta to build the voltaic pile to prove that electricity did not come from the animal tissue but was generated by the contact of different metals, brass and iron, in a moist environment. Ironically, both scientists were right.

Named After Alessandro Volta
voltThe unit of electromotive force, or difference of potential, which will cause a current of one ampere to flow through a resistance of one ohm. Named for Italian physicist Alessandro Volta.
PhotovoltaicPhotovoltaic are systems that convert light energy into electricity. The term "photo" is a stem from the Greek "phos," which means "light." "Volt" is named for Alessandro Volta, a pioneer in the study of electricity.

Alessandro Volta was born in Como, Italy in 1745. In 1774, he was appointed as professor of physics at the Royal School in Como. While at the Royal School, Alessandro Volta designed his first invention the electrophorus in 1774, a device that produced static electricity. For years at Como, he studied and experimented with atmospheric electricity by igniting static sparks. In 1779, Alessandro Volta was appointed professor of physics at the University of Pavia and it was while there that he invented his most famous invention, the voltic pile.

Philip H. Diehl (29 January 18477 April 1913) was a German-American engineer and inventor who held several U.S. patents, including electric incandescent lamps, electric motors for sewing machines and other uses, and ceiling fans. Diehl was a contemporary of Thomas Edison and his inventions caused Edison to reduce the price of his incandescent bulb.

The electric fan was invented in 1882 by Schuyler Skaats Wheeler. A few years later, Philip Diehl mounted a fan blade on a sewing-machine motor and attached it to the ceiling, inventing the ceiling fan, which he patented in 1887. Later, he added a light fixture to the ceiling fan. In 1904, his Diehl and Co. added a split-ball joint, allowing it to be redirected; three years later, this developed into the first oscillating fan.

Earle Dickson invented this protective cover made of adhesive for cuts and sores, with the intention of saving the fingers of his wife. Earle Dickson worked as a cotton checker for the firm of Johnston and Johnston when he invented the band-aids 86 years ago in 1921. His wife, Josephine Dickson was always cutting her fingers when she prepared meals in the kitchen.In those days, covering a wound was done by using a piece of gauze with adhesive tape placed on top to keep it in place. Earle Dickson noticed that the gauze and adhesive tape that his wife used fell off in no time because of the work she had to do with the fingers. So he decided that there had to be a way of protecting small wounds more effectively..

Where did Silly Putty come from?
Silly Putty started as a mistake in a New Haven laboratory, and turned into a consumer hit in the 1960s by sheer chance. According to engineers, Silly Putty is a self-contradiction. Chemically, it is a liquid, but it resembles a solid. The molecular structure will stretch if the structure is slowly pulled. But if tugged, it snaps apart. The toy has a rebound capacity of 75 to 80 percent, whereas a rubber ball has only about a 50-percent bounce-back. A silicon derivative, Silly Putty won't rot; it can withstand temperatures from -70 degrees Fahrenheit to hundreds degrees above zero. On top of all that, it picks up newsprint, often sharper than the original.

Credit for the invention of the parachute goes to Sebastien Lenormand in 1783. In 1495, Leonardo da Vinci designed a pyramid-shaped chute. J. P. Blanchard (1753-1809), a Frenchman, is said to have been the first to use a parachute. In 1785, he dropped a dog in a basket, to which a parachute was attached, from a balloon high in the air. Blanchard claimed to have descended from a balloon in a parachute in 1793.

In the month of February, 1946 the ENIAC was near completion. It was considered the first electronic organizor in history. With a heart of valves, the ENIAC was able to calculate 5,000 math and 300 multiplications. Due to this, the evolution of the electronic calculators took an accelerated level – that of miniaturization of component. The velocity of the large scientific organizors was duplicated every 2 years and the super organizor actually is seven million times faster than the ENIAC.

In 1679, the physcist and mathematician, Denis Papin, who was Anglo French (1647-1712) invented the stream pot — which he clled the digesteur. In this pot water was boiled at a temperature higher than normal. In this way meat and other foods were cooked in less time than when cooked in conventional pots of that time. Mr. Papin presented his invention to the Royal Society in London in 1681, but the novelty did not become popular and as a scientific study. Nevertheless this work served to admit him as a member of that scientific society. The wworld then had to wait until the 20th Century for this invention to be made and used as the PRESSURE COOKER.

The unexpected has finally come to past. The day when someone will look me in the face and say on of my blogs is an abuse of my position. People, the last time I checked I lived in a free society in a free world and I was allowed freedom by the blogspot on the internet to voice my opinions and to try to help others to learn. I pray the readers out there will see what I am saying and tell me if there has been anything on these blogs of mine that has misled anyone. I am a teacher by profession and director of the school in which I teach and one I am ashamed of my profession at the moment. You will ask why I am ashamed. My answer is because if a colleague can look me in the face and write on paper that I am abusing my position with the use of these or any of my blogs or website when all I set out to do was to help my students and to give some colour to their little Corozal Town lives, then there is something wrong with the educational system in which I live. Either it will have to go or I will.

This is the why wars begin. People misunderstand things because they are told a lot of rubbish and ideas are pushed into their already packed brain. I urge each and everyone to stop and think before they listen to others. Ask yourself why is this person doing this and what is the hidden agenda? People do things for different reasons. Think. Why would someone who is supposed to be a friend or was a friend at one time, of another person, suddenly turn on him or her?

I will tell you right now if I am told that this entry was wrong to write there will be a lot of changes in Belize very soon. My democratic right as a citizen in a free country must never be taken for granted. I may be a lot of things to different people, but I am a caring, honest teacher and Director. I fight for the right to learn and to have choices that will assist students to become strong men and women of Belize. It was my hope that one day someone out there would see these blogs and want to assist the school or students. THAT WAS MY HOPE. IT IS STILL MY HOPE AND I WILL TRY MY BEST TO SEE SOMETHING POSTIVE IN REGARDS TO THE BLOGS so they are not WRITTEN IN VAIN.

If you asked me why I began the blogs I would have to honestly say because Mr. Abel Lopez Rodriquez showed me how to do them. Abel is a person who sees the good in everything and everyone. I have had to tell him more than once that there are people who are around who are dangerous, conniving and just plain mean. All that sea breeze must be getting to the brain and causing a deficiency called “deception”. Trust me there will be no forgiving from now on.

Write me at and visit my website and tell me if I am abusing my connections with my school. I am calling on all bloggers to give me a hand on this. Give me the ammunition I need to fight back to save my blogs and myself. Today it is me, but tomorrow it can be YOU.

Thank you,
Brenda A. Ysaguirre
Director, ACE

Although the function of the zipper appears to be very simple, at first it was not. The first zippers were completely different from the ones we have today. In 1912 Gideon Sundback perfected this invention he placed it on the market the next year. Today there is a large number of different models of zipper that are used in the textile industry for pants, military uniforms and boots.

Inventions that Changed the Course of Humanity!!
In 1937, in the United States of America, began the sale of heaters that produced hot air with the aid of electricity. Soon the system was added to a circuit attached to a container of water. This produced heat to the water. It was made with the use of gas, firewood, electricity, carbon etc... It became of great use in those countries where the temperature drops to a large extent. The heater has gone through many designs since its creation.

Exactly one can not speak of the inventor or the exact time of the discovery of the light bulb. In the early years filaments were used. These were some charred strips of paper, which didn't last very long. In 1913 the American, Irving Langmuir placed within bulbs nitrogen and argon for slower evaporation. In 1934 was began the use the filament which was doubly coiled. This gave rise to the current bulbs and there are a lot of patterns and shapes.

Guillermo González Camarena, Mexican scientist and inventor in 1934 fabricated his own television camara at the age of 17. He began to improve his television equipment and with his idea of giving it colour he produced a system called "Sistema Tricromático Secuencial de Campos, " in Spanish. This made the commission in charge of patents see that it was possible to adapt this system to the black and white television. They declared that the emission of televison services

was a contribution by John Logie Baird.

Antonio Meucci, the great Italian Inventor, had a career that was at the same time extra-ordinary and tragic. An emigrant to New York, Meucci continued without ceasing and with vigour, a project he had began in Havana, Cuba. It was the invention later called the teletrophone, and was related to electronic communications. Antonio Meucci configured a rudimentary line of communication in his house on Staten Island which connected the lower storey of the house with the first. Later, when his wife began to suffer arthritis which prohibited her from moving, Meucci created the permanent connection between his laboratory and his wife’s bedroom on the second floor of the house. Having spent a major part of his savings to finance his work, Meucci was unable to commercialize his invention, although he announced it to the public in 1860. Unfortunately his decription and publication in the New York Times was written in Italian.Antonio Meucci never learnt English enough to comunicate with the business society of the United Status of America. He was unable to attain sufficient funding for the necessary paperwork to process his patents, and due to this had to ask for a “renewable reserve” which for a year impeded anyone from presenting a similar patent. This petition was presented first on the 28 December, 1871. Meucci later discovered that the laboratory afiliated to Western Union had lost the models of his work. As Meucci was at this time living on public assistance, he was unable to renew his “reserve” after 1874.
In March, 1876, Alexander Graham Bell, who had done some experiments in the same laboratory where Meucci had worked on his, obtained a patent and recieved the credit for the invention of the telephone. On the 13th January, 1887, the Government of the United States of America tried to annul the patent Bell had gotten on the grounds of evidence of fraud and distortion. The case was found viable by the Supreme Court and for it Bell suffered the penalty of imprisonment. Meucci died in 1889, and Bell’s patent expired in 1893. The case was suspended on the grounds of doubt, without ever determining who the real inventor of the telephone presented in Bell’s patent was. Actually, if Meucci had been able to pay the fee of $10 to maintain the “reserve” on his invention, the laW would have been unable to assign Bell any such patent.

(Note: $10 back in those days was a lot of money)

We are still trying to blame someone for this one! I think the cavemen were responsible and quite frankly I am not happy with them at all. There should have been a quesionnaire handed out to us before we got to accept having a job, having harsh bosses and most of all having to deal with people who drive us up a wall.

Don't get me wrong. I love my job and I am a workaholic but all the mishaps in the work place are created by the influences of the working mass.
Why couldn't we have a peaceful, carefree, no WORK, LIFE???

Maybe you disagree with me and are happy work was invented. If so, smile, keep on working adn have a great day.

With Love,

Brenda Aurora Ysaguirre
