![]() ![]() In 1990, the Hubble Space Telescope was carried into orbit by the Space Shuttle. It was completed in 1957 and had a 250-foot diameter radio dish that could be aimed into the sky. Over the next 400 years, there have been astronomical advances, but all of the telescopes have two things in common: they have light gathering abilities and they magnify.ĭuring WWII, Sir Bernard Lovell had worked on radar and after the war in the 1950s he made plans for a large radio telescope. In 1789 in England, William Herschel built the first giant reflector telescope, which was 12 meters long. His new improved telescope eliminated chromatic aberration, was cheaper to build, simpler in design, had a wider field of view, and was portable. ![]() This coloring is called chromatic aberration and it causes fringe coloring, so that images look blurred. Newton’s idea was to use mirrors so that the creation of colors by the lens could be eliminated. Up to that point, telescopes were refracting and used a lens which worked much like the prisms Newton was using. In 1668, Sir Isaac Newton built the first reflecting telescope in order to prove his theory that white light had a spectrum of colors. He drew the moon’s phases, was able to describe the Milky Way, and discovered the rings of Saturn and the moons of Jupiter.īecause he became convinced that Earth and the planets circled the Sun, he was arrested by the Catholic Inquisition and imprisoned until he died in 1642. In 1609, Galileo heard about Lippershey’s invention and began building his own design making many improvements so that the magnification of his telescope reached 20 times.Īccording to history, Galileo looked to the skies and was able to see the craters of the moon. His ‘looker’ was made by fitting one concave piece of glass to a convex piece of glass. He called his invention the ‘looker’ and was able to magnify things to three times their normal size. We just use other mirrors to flip it back.The first person to patent a telescope was Hans Lippershey, a Dutch eyeglass maker, in 1608. Have you ever looked into a spoon and noticed your reflection is upside down? The curved mirror in a telescope is like a spoon: It flips the image. ![]() Also, since mirrors are one-sided, they are easier than lenses to clean and polish.īut mirrors have their own problems. It is much easier to make a large, near-perfect mirror than to make a large, near-perfect lens. So the mirror just has to have the right curved shape. Light is concentrated by bouncing off of the mirror. A bigger mirror does not also have to be thicker. Unlike a lens, a mirror can be very thin. ![]() It would be like looking through a dirty window.Ī telescope that uses mirrors is called a reflecting telescope. Any flaws in the lens will change the image. Also, as they get thicker the glass stops more of the light passing through them.īecause the light is passing through the lens, the surface of the lens has to be extremely smooth. Heavy lenses are hard to make and difficult to hold in the right place. If you want to see far away, you need a big powerful lens. People with especially poor eyesight need thick lenses in their glasses. In a telescope, it makes faraway things seem closer.Ī simple refracting telescope uses lenses to make images bigger and more visible. In eyeglasses, this makes things less blurry. It’s hard to make a perfect mirror, but it’s even harder to make a perfect lens.Ī telescope made with lenses is called a refracting telescope.Ī lens, just like in eyeglasses, bends light passing through it. If they do have such problems, the image gets warped or blurry and is difficult to see. They can’t have any spots, scratches or other flaws. That means the mirrors and lenses have to be just the right shape to concentrate the light. The optics of a telescope must be almost perfect. That light is what we see when we look into the telescope. Light is then concentrated by the shape of the optics. The bigger the mirrors or lenses, the more light the telescope can gather. To do that, the optics-be they mirrors or lenses-have to be really big. The mirrors or lenses in a telescope are called the “optics.” Really powerful telescopes can see very dim things and things that are really far away. So why do we use mirrors today? Because mirrors are lighter, and they are easier than lenses to make perfectly smooth. The first telescopes focused light by using pieces of curved, clear glass, called lenses. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. A telescope is a tool that astronomers use to see faraway objects. ![]()

Indeed the military has significantly increased its efforts to protect the project. Another stated, “70 people killed in Quetta and the army chief only talks about CPEC”. “China ignores human rights issues in Balochistan, but unless we do something for the local people CPEC will not succeed,” a professor in Islamabad told ECFR. So far China’s only response to the complex issues and disputes in Balochistan has been to call on Pakistan’s army to ensure security. ![]() The question, however, is how many Baloch (or other minorities) are educated and skilled enough to qualify for these new jobs. Estimates of CPEC creating up to two million jobs may be exaggerated but, nevertheless, there will be newly created job opportunities in fields ranging from construction and engineering to architecture and IT. One of the dilemmas might be the lack of skilled and educated people in such underdeveloped regions. The latter refers not only to including local voices in the decision-making process of CPEC but also failing to include local people in newly created jobs. “The problem so far is that Chinese investment is focused on monumental infrastructure and not on rural development”, ECFR was told by an academic in Pakistan, and that “the locals have no role” in CPEC. Increasingly, the CPEC has been a target for domestic political opposition in Pakistan, amid fears that the $46 billion package of Chinese investment will be distributed inequitably and fail to benefit those communities, which need it most -in particular Balochistan, but also Gilgit-Baltistan and Khyber Pakhtunkhwa. However, several observers in Pakistan interviewed by ECFR experts recently warn that the CPEC might exploit Balochistan rather than develop it, while the government in Islamabad and other provinces benefit the most. The CPEC could be a major driver of employment for those underdeveloped regions. Islamabad hopes that the region will become a major trading hub, linking the deepwater port of Gwadar with the Western Chinese province, Xinjiang, via the CPEC. It was repressed by the Pakistani state until recently, when the conflict shifted to a battle for control of the region’s rich resources, at the centre of which lies the CPEC. The Baloch insurgency, a result of ethnic nationalism, peaked in the 1970s, at the time of the creation of Bangladesh. It is rich in natural resources, like oil, gas, copper and gold, and yet it is one of the poorest regions of the country. It constitutes half of the country’s landmass, but only 3.6 per cent of its total population. After the Partition of India, the province, which comprised of four princely states and was guaranteed independence, was forcefully occupied by Pakistan in 1948. In reaction to the suicide bombing in Quetta, European Parliament member Alberto Cirio urged the international community “to take notice of a situation created due to years of concerted government use of extremist groups as proxies against political activists, journalists and intellectuals.”īalochistan’s troubles stem from its fraught history and many paradoxes. The government and military have also been implicated in human rights violations in Balochistan, with Human Rights Watch accusing Pakistani security forces of “continue to unlawfully kill and forcibly disappear suspected Baloch militants and opposition activists in 2015”. In addition, Balochistan has seen numerous attacks by Islamist militant groups, including the August bombing of the government hospital in the province’s capital Quetta, which was carried out by Pakistani Taliban groups. ![]() Several militant separatist groups are responsible for various attacks against Pakistani security forces and construction workers. With rising political tension in the region, brought to the fore by the ambitious China-Pakistan Economic Corridor (CPEC), the central players, Pakistan and China, are contending with many unexpected factors, including India.īalochistan is one of the least developed and most troubled areas of Pakistan, having witnessed regular insurgencies and military campaigns. Could the Great Game in Asia shift from Afghanistan to Balochistan? According to watchers of the complex geostrategic region, including a former general of Pakistan’s army, it already has. ![]() ![]() This is played in the upper range of instruments, such as guitars or violins. 3,000 Hz – 8,000 Hz: Upper mid-range frequencies.Most instruments, such as guitars and pianos, are played in this range. This is the range we are used to hearing, and vocal sounds are located in this range. 600 Hz – 3,000 Hz: Mid-range frequencies.You’ll hear this range of frequencies if you play the lower end of many musical instruments, such as guitars or a piano. 200 Hz to 600 Hz: Low mid-range frequencies.60 Hz to 200 Hz: Low frequencies requiring a bass or lower drums to be reproduced.Only sub-bass and kick drums reproduce these frequencies, and you need a subwoofer to hear them or a good pair of headphones. 20 Hz – 60 Hz: Super low frequencies on the EQ.That’s why you always see small speakers around your surround sound but a colossal bass speaker to give some punch. Low-frequency sounds require more power and bigger speakers, while higher-frequency sounds require less energy and smaller speakers. ![]() Simply put, if you have a low-frequency sound, you’ll hear waves in the bass or sub-bass range.

You can also find equalizers in most stereo sound systems, Blu Rays, Smart TVs, Car stereos, etc. Still, since most audio is consumed digitally nowadays, equalizers have been implemented in most devices, such as computers, smartphones, etc., to allow you to adjust your audio settings and get the most out of your speakers. It usually works with frequencies between 20 Hz to 20,000 Hz, which are theoretically the frequencies humans can hear, although, in reality, our range could be decreased by age and other factors.ĭecades ago, equalizers were managed via a physical console where you could tune up and down levers to adjust your settings.

Those plans involve an overhaul of the long-closed restroom building, a regrading of much of the damaged asphalt flooring in the area, and the installation of several new trees to beautify the location. In addition to the sweeping plans to renovate the area on 88th Street, a city official also came to discuss plans to upgrade the Bayside Playground near Scholar’s Academy on Beach Channel Drive between Seaside Ave and Beach 104th Street. While the space is relatively empty aside from the Community Boathouse kayak area, the city plans to install a steel, concrete, and recycled plastic playground area, binoculars for some scenic views of the Manhattan skyline, drinking fountains, tables, and a fishing area to turn it into a fully functional city park.Īnd for those who might be worried about what will become of the Community Boathouse once the new park is put in place, fear not!
