The natural substances can be the dust, cockroaches, animal dander, mold or pollen. As it is very will known cold is contagious while allergy is not.

There are three common symptoms between cold and allergy which are sneezing, runny nose, fatigue and congestion. While there are other symptoms that differ between allergy and cold.

There are symptoms than appears mostly in the cases of allergies and rarely in the cases of cold as itchy eyes, watery eyes, itchy throat.

There are symptoms than appears mostly in the cases of cold and sometimes in the cases of allergy as fever, cough, sore throat, pain all over the body and headache.

Treating cold is by resting, taking pain relieves and cold fighting medicines, while the allergy needs other sorts of medication such as antihistamines and a more important factor which is avoiding the cause of allergy.

Signs For Heart Attacks

Signs For Heart AttacksHeart attacks are very tricky as the heart attack symptoms could be similar to other symptoms that represent fatigue, severe indigestion or shortness of breath. Symptoms of heart attack can be mild or intense and might be slow or sudden. Some people have heart attacks with no pain at all. The factors that can more people more vulnerable to heart attacks than others are diabetes, obesity, high blood pressure, high alcohol consumption, age and heredity. Diabetic people are more exposed to have heart attacks without any symptoms at all.

There are many symptoms that can point to heart attack, the most common are:

  • Fast or irregular pulse is a sign of heart attacks if it is frequent or accompanied with dizziness, weakness or fatigue.
  • Sweating cold sweat in times that person is not making efforts.
  • Anxiety, trouble sleeping and fearing death.
  • Fatigue or weakness without doing a big effort can be a sign for heart attack.
  • Coughing persistently can be a sign for a heart you should not ignore.
  • Dizziness can be caused by heart attacks.
  • Disturbance in the breath that sometimes can be mistakenly diagnosed as asthmas can be a symptom of heart failure or heart attack.
  • The swelling in the abdomen or swelling of the feet, legs or ankles can be caused due to heart attacks.
  • Nausea, vomiting, loss of appetite or indigestion can happen before a mild heart attack would start.
  • Pain starts in the chest then spread in different places of the body as neck, back, throat, jaw, teeth, abdomen one or the two shoulders or arms.

In case of the happening of a heart attack, you should follow your doctors directives if you are a patient with heart problems, if not a couple of aspirins can help till the patient is transferred to a hospital which has to be immediately. Knowing CPR can help you save persons having heart attacks.

Inventions Discovered By Chance

The microwave oven

Visiting a laboratory, Percy Spencer, an American scientist , discovered in 1945 a strange phenomenon. He noticed that the chocolate bar he kept in his pocket began to melt quickly. He was not the first to notice this, but he was the first to investigate. He did an experiment with an egg:

He placed the egg in in a tea kettle, and the magnetron was placed directly above it (Magnetron is An electron tube for amplifying or generating microwaves, with the flow of electrons controlled by an external magnetic field).

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. He then repeated the experiment with corn grain. He got popcorn in seconds.

Discovered by Georges De Mestral. Walking in the woods, the Swiss engineer observes that burdock clings to his corduroy trousers. Intrigued, he looked more closely at the form of the plant hooks and loops of the fabric of his pants. So he invented Velcro which is the shortcut to mean velvet hook.

Potato Chips
During the summer of 1853 the restaurant ‘ Moon Lake Lodge’ in Saratoga Springs, New York , the United States, a client accused the cook of bringing him too thick fries . A new service was presented to him with more fried thinly sliced ​​. But they met with the disapproval of this devious client. The chief decided then to prepare a very thin sliced of chips, crunchy and hard. The following day, the restaurant was surprised of the increasing strong demands of chips lovers in the restaurant.

Coca -Cola
Styth John Pemberton, a pharmacist in Atlanta (Georgia), wanted to create a new drug, a kind of refreshing syrup. He developed a mixture of kola nut extract, sugar, caffeine, coca leaves and plant extracts. The beverage is sold at the ‘soda -fountain ‘ of Jacob ‘s Pharmacy. Then he got the idea to dilute the syrup with carbonated water, and that’s when Coca- Cola was being invented.


It was invented by Thomas Edison involuntarily seeking in 1877 to record telegraph messages. He recorded it for the first time in the history of humanity, a human voice, his voice.

inkjet printer
Inkjet printer

A Canon engineer discovered it accidentally. He had left a hot soldering iron next to his pen, The pen has responded by spitting ink moments later. Thus, this is how the Inkjet Printer was invented and developed.


Alfred Nobel had a nitroglycerin plant. He was working on a formula to make the nitroglycerin more stable, because it is known to jump randomly. He accidentally dropped a bottle of nitro that slipped in sawdust, and did not explode. Later, he refined his recipe and this explosive paper wrapped in stick form is called “dynamite” and patented in 1867.



In 1859, Robert Chesebrough wanted to get rich thanks to oil in Pennsylvania. Finally he did not really find the famous black and gold, but a yellow viscous substance. Back to his laboratory in New York, he found (after oil insulation) that is a good balm for healing cuts and scrapes (first applications found). Chesebrough ate a spoonful of vaseline every day until his death.



Originally researchers Pfizer wanted to develop a treatment for angina pectoris (heart disease). In clinical trials, the treatment did not have the desired effect. However, they were surprised to see that it caused an erection. They decided to reposition the treatment and viagra arrived in the U.S. in 1998 and Europe in 1999.

Sources Of Electricity

We can get electricity from hydrocarbons, chemical reactions, magnetism, nuclear reaction, water, sun and air.

Coal, oil and natural gas are the unclean source of electricity, hydrocarbons are the most used method to generate electricity and the cheapest. But hydrocarbons are the main source of global warming and pollution.

Chemical reactions is the source of electricity we see in batteries. The idea is transferring the chemical energy to electrial energy. The chemical energy can also be produced by the galvanic cell.

Electricity generator depends on magnetism in order to produce electricity. The magnetism power is produced when rotating a magnet in closed loops.

Nuclear energy is another source of producing electricity, by cutting the bonds in some materials especially Uranium a huge amount of power is released. But due to the great dangers that can occur it is not used in wide scales.

Kinetic energy is formed due water moves as flows downstream, falls, tides and waves. The energy from the water moving can be transferred to electricity using turbines.

Using Sun in producin‌g electricity is a clean method also a renewable , solar energy can be transferred to electricity using photovoltaics and semiconductors. Mirrors can
be used as a concentrator factor.

Air is another clean and renewable source for producing electricity, using windmills has proven to be successful several places worldwide. Windmills farms are  now put in the unused spaces including seas and oceans. But still it is not a very popular source of generating electricity due to the inability of controlling the direction of the wind.

Modern Inventions For Blind

A Bionic Eye For The Blind – Israeli Invention

Israeli Scientists have developed a technology that allows blind people to see with the help of a bionic lens contact.

The new technology, developed by a team from the Bar-llan University, has yet to receive the approval of clinical trials, but its feasibility is currently being tested using a model simulating the bionic lens.

The technology consists of a small camera that received visual information from the environment and transmits signals to a bionic lens contact. the lens passes the signals via the electrodes to the cornea and from there to the sensory brain areas, generating a stimulus that simulates the visual information.

Professor Zeev Zalevsky, head of electrical engineering and nano-photonics at Bar-llan University and leader of research team said:”This technology is a god news for humanity, especially to give sight to the blind without surgery or damage to other vital organs or sense”.

The first Smartphone for the blind waiting for the end of 2013

A young Indian inventor is trying to develop a unique smartphone, for the blind which are about 20 million in India.

Read his messages, reply, listen to music or just surf the web with your smartphone. Many daily actions that you now seem completely banal, but who are not blind. While many applications allow them to use smartphones, but none of these smart phones is really adapted to their disability.

Not for long: a young inventor Indian Sumit Dagar, has devised a smartphone accessible to blind, has a touch screen that can read Braille, tactile writing system used by the blind people can be read on the website of Indian Times. Better, the same prototype give the opportunity to guess the fingertips of photos or maps.

An introductory price estimated at $ 185

In terms of technology,  Short development, this smartphone could hit the market by the end of 2013, with an introductory price estimated at 185 dollars (142 euros), according to several specialized sites.

According to the World Health Organization (WHO), 285 million people are visually impaired worldwide: 39 million are blind and 246 million are visually impaired. A niche market, in fact.
