When was the first compass made?

the compass first appeared during the Han dynasaty(202BCE-220BCE) in china. However, it could have been invented by either the Chinese or the indiand, as both stated using it about the same time.

How do you make polariscope for honey grading?

Building a polariscope can be as easy or complex as you like. On the easy side just having a very bright light source behind a set of polarizing photography filters will work for what you are trying to do. Make a bracket to hold all the elements of the polariscope and then assemble it. Of course it would be a smaller unit but for most uses in honey with such a device are small. If it would need to be a larger device you are going to need a good solid foundation on which to build it. Usually they are build from a good high quality wood and then photo grade polarized glass is put into the frame work and spun around to the point it is needed and then firmly held in place and the whole unit is enclosed other than the "stage" where you are setting the honey to be observed. The main elements in the polariscope for honey observation are polarized glass 2 pieces to run the light through to get it to the right wavelength and a powerful light source.

What year was the hubble telescope invented?

The Hubble Telescope was sent into space in 1990. It was designed and built for several years before that. As of 2014, it is still in operation.

Do lightsabers exist?

As seen in the star wars series, no. However, The Berkly institute has developed a contained plasma arc device that looks, sounds, and behaves much like a light saber. It is far from portable though, as it takes a massive amount of power to operate as well as equipment the size of an SUV, not a flashlight.

Who invented street lights?

Franz von Drais, a German inventor, is credited with being the first to introduce street lights in 1817. However, the modern electric street light was invented by Thomas Edison in the late 19th century.

If you were in an airplane with a maximum speed of 600 miles per hour and you were traveling in the direction opposite the earth's rotation could you travel fast enough to never see the sun set?

If you were going fast enough. But if you want too fast I imagine you would see western sunrise again. However at that speed you would run out of fuel quite fast. It would depend upon your latitude and the time of year. For example if you were above the Arctic circle in the summer, any speed would keep you in the light, but in the winter you would always be in the darkness. The farther away you are from the equator the slower you could travel. (Assuming you are traveling parallel to the equator.) The necessary speed at the equator is approximately 1038 MPH.

Who invented the solar cooker?

The concept of solar cooking has been used for centuries, with various designs and adaptations throughout history. It is difficult to pinpoint a specific individual as the sole inventor of the solar cooker. However, notable advancements in solar cooking technology have been made by many individuals and organizations over time.

How much was Percy shaw paid per mile for his invention of cats eyes?

That's a fable.

Percy Shaw's was never offered a 'per mile deal' for this invention of Cat's Eyes by the British government or anyone else.

Percy Shaw could have made a lot more money from the royalties of his invention had he allowed it to be manufactured abroad. However since, in his words, he didn't trust foreigners except to make the face plates, the money he made was always limited because he insisted on only allowing the supply of Cats Eyes glass and their rubber housings to be manufactured in his factory.

What were some inventions in 1969?

Some inventions in 1969 include the ATM (Automated Teller Machine), the microprocessor, and the UNIX operating system. Additionally, researchers at CERN developed a precursor to the World Wide Web, known as ARPANET.

Why is a microscope important to scientists?

It is important because it helped us discover bacteria, fungi, medicines, and other microscopic organisms. The discovering of the bacteria helped the doctors find cure for the diseases. Without the microscope you would be dead by any kind of disease or sickness!
because the microscope was the item that first helped man discover cells and the microscope can assits in diagnosing disease, investigating a crime sceen(or evidence from a crime sceen) and many other things

Who made the first hot air balloon?

The Montgolfier brothers Joesph and Michael made the first manned hot air balloon but the Robert brothers and Jacques Charles made the first manned hydrogen balloon

What are the different types of sundials?

The main types of sundials are horizontal, vertical, equatorial, and polar. Horizontal sundials are the most common and have a flat plate with hour markings. Vertical sundials have a vertical dial face and are often found on walls or pillars. Equatorial sundials have a dial plate that is parallel to the equator, while polar sundials are aligned with the Earth's axis.

What was the name of the space ship that took the first two men to the moon in 1969?

The name of the spaceship that took the first two men to the moon in 1969 was Apollo 11. The astronauts were Neil Armstrong and Edwin "Buzz" Aldrin.

Where and when was the first lamp made?

Lamps have been around from the time that man harnessed fire. Lamps made of wood, grass, straw, animal fats were all used. Oil lamps made use of a wick that would supply a flame with a oil from an oil reservoir and this is perhaps the first of the low maintenance lamps. In the early 1800s, a lamp that burnt hydrogen with calcium oxide (lime) was developed and is known as a limelight. They were often used in theaters because of their intense light output. The phrase "in the limelight" was coined because stars were lit by limelight on stage. As electricity became available, high power lamps used an arc, or a spark between two electrode to create light. Arc lamps became available in the mid 1800s but were difficult to maintain Thomas Edison, an American inventor from Ohio is generally credited with the invention of the incandescent light bulb. He patented the idea in 1880 after thousands of experiments that involved a high resistance wire in a glass bulb. The early experiments were successful but only for a few minutes. The final product was able to operate for many hours rather than minutes. Edison was the first to produce a compact and reliable incandescent lamp. It is interesting to note that at least 20 others tried and succeeded in similar endeavours. Edison was granted his patent for the first practical incandescent lamp. Edison joined forces with another inventor called Swan. Their company later became known as Thorn Lighting Ltd, still around today.

When was the contact lens invented?

The concept of contact lenses was first introduced in 1508 by Leonardo da Vinci. However, the modern version of contact lenses was developed in the late 19th and early 20th centuries by various scientists and inventors, with the first commercially successful contact lenses introduced in the 1940s.

Who invented infrared goggles?
