Mount Kilimanjaro
Mount Kilimanjaro (), with its three volcanic cones, "Kibo", "Mawenzi", and "Shira", is a dormant volcano in Tanzania. It is the highest mountain in Africa, about from its base to above sea level. The first people known to have reached the summit of the mountain were Hans Meyer and Ludwig Purtscheller in 1889. The mountain is part of the Kilimanjaro National Park and is a major climbing destination. The mountain has been the subject of many scientific studies because of its shrinking glaciers and disappearing ice fields. Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at ; and Shira, the shortest at .
Chaga people
The Chaga (also called Wachaga, Chagga, Jagga, Dschagga, Waschagga, or Wachagga) are Bantu-speaking indigenous Africans and the third largest ethnic group in Tanzania. They traditionally live on the southern and eastern slopes of Mount Kilimanjaro and Mount Meru and near Moshi. Their relative wealth comes from the favorable climate of the area and successful agricultural methods, which include extensive irrigation systems, terracing, and continuous organic fertilization methods practiced for thousands of years. They were one of the first tribes in the area to convert to Christianity. This may have given them an economic advantage over other ethnic groups, as they had better access to education and health care as Christians.
Tanzania
Tanzania (), officially the United Republic of Tanzania (), is a sovereign state in eastern Africa within the African Great Lakes region. It borders Kenya and Uganda to the north; Rwanda, Burundi, and the Democratic Republic of the Congo to the west; Zambia, Malawi, and Mozambique to the south; and the Indian Ocean to the east. Mount Kilimanjaro, Africa's highest mountain, is in north-eastern Tanzania. The United Nations has estimated Tanzania's population at /1e6 round 2 million. The population is composed of several ethnic, linguistic, and religious groups. Tanzania is a presidential constitutional republic, and since 1996, its official capital city has been Dodoma, where the president's office, the National Assembly, and some government ministries are located.
Moshi, Tanzania
Moshi is a Tanzanian municipality with a population of 184,292 according to the 2012 census. The municipality is in the Kilimanjaro Region and is situated on the lower slopes of Mount Kilimanjaro, a dormant volcano that is the highest mountain in Africa. The municipality covers about and is the smallest municipality in Tanzania by area. Many people from the Chagga and Pare ethnic groups live in Moshi, which lies on the east-west A23 Arusha–Himo road connecting Arusha and Voi, Kenya. Just to the east of Moshi is the intersection with the B1 north–south road eventually connecting with Tanga and Dar es Salaam.
Northern Ice Field (Mount Kilimanjaro)
The Northern Ice Field is near the summit of Mount Kilimanjaro in Tanzania, on the west slope of the peak. The Northern Ice Field and Eastern Ice Fields were connected to the Southern Ice Field and formed part of a continuous body of glacial ice atop Mount Kilimanjaro when first scientifically examined in 1912. By 1962 the Southern Ice Field separated from the Northern Ice Field and then by 1975 the Eastern Ice Field did as well. In 1912, the glaciated areas atop Mount Kilimanjaro covered ; by 2011 this had been reduced to , an 85 percent loss. At one time, ice flowing off the Northern Ice Field fed numerous glaciers, including, north to south, the Credner, Drygalski, Great Penck and Little Penck Glaciers.
Mount Kilimanjaro climbing routes
There are several routes by which to reach Kibo, or Uhuru Peak, the highest summit of Mount Kilimanjaro, namely, Marangu, Rongai, Lemosho, Shira, Umbwe and Machame. Being one of the most popular mountains in the world, roughly 50,000 trekkers every year try to reach the summit of Mt Kilimanjaro. According to research published by the Climb Kilimanjaro Guide, the average summit success rate across all climbers and routes is 65%. However, summit success rate heavily depends upon what route is climbed as routes vary considerably in terms of acclimatization profile and duration of climb. The Lemosho route approaches Kilimanjaro from the west.
Tourism in Tanzania
Tanzania is a country with many tourist attractions. Approximately 38 percent of Tanzania's land area is set aside in protected areas for conservation. There are 16 national parks, 29 game reserves, 40 controlled conservation areas (including the Ngorongoro Conservation Area) and marine parks. Tanzania is also home to Mount Kilimanjaro, the highest point in Africa. Travel and tourism contributed 17.5 percent of Tanzania's gross domestic product in 2016 and employed 11.0 percent of the country's labor force (1,189,300 jobs) in 2013. The sector is growing rapidly, rising from US $1.74 billion in 2004 to US $4.48 billion in 2013.

Omar Samra
Omar Samra (born 11 August 1978) is an adventurer, mountaineer, entrepreneur, inspirational speaker and future astronaut. He is the first Egyptian to climb Mount Everest, the 7 Summits and ski to both the Geographic South and North Pole (The Explorer's Grand Slam). He reached the summit of Mount Everest at 9:49 am Nepal time (roughly 7:19 am Egyptian time) on 17 May 2007. He is also the first Egyptian to complete the 7 Summits challenge on 31 May 2013, climbing the highest mountain on all 7 continents. On 5 December 2013, he was chosen to be an astronaut to become the first Egyptian in space sometime in 2016.
List of deaths on eight-thousanders
The eight-thousanders are the 14 mountains that rise more than above sea level; they are all in the Himalayan and Karakoram mountain ranges. This is a list of mountaineers who have died on these mountains. Mount Everest, Earth's highest mountain, has been host to numerous tragedies; over 280 have died on the mountain, with deaths occurring every year since 1978. The most notable events occurred during the 1922 British Mount Everest Expedition, 1970 Everest Disaster, 1974 Everest Disaster, 1996 Everest Disaster, 2014 Mount Everest avalanche, and 2015 Mount Everest avalanches. See the complete list of people who died climbing Mount Everest.
Seven Summits
The Seven Summits are the highest mountains of each of the seven continents. Summiting all of them is regarded as a mountaineering challenge, first achieved on 30 April 1985 by Richard Bass. The Seven Summits achievement has become noted as an exploration and mountaineering accomplishment. The Seven Summits are composed of each of the highest mountain peaks of each of the seven continents. Different lists include slight variations, but generally the same core is maintained. The seven summits depend on the definition used for a continent — in particular the location of the border of that continent.
Yes (band)
Yes are an English rock band formed in London in 1968 by singer Jon Anderson, bassist Chris Squire, guitarist Peter Banks, keyboardist Tony Kaye, and drummer Bill Bruford. The band have undergone numerous formations throughout their history; nineteen musicians have been full-time members. Since June 2015, it has consisted of guitarist Steve Howe, drummer Alan White, keyboardist Geoff Downes, singer Jon Davison, and bassist Billy Sherwood, with no remaining founding members. Yes have explored several musical styles over the years, and are most notably regarded as progressive rock pioneers. Yes began in 1968, performing original songs and rearranged covers of rock, pop, blues and jazz songs, as evident on their first two albums.
Hill people
Hill people is a general term for people who live in hills and mountains. There are a wide variety of hill people around the world, many of whom live by small scale pastoralism or on small farms. Musical instruments of hill people, such as various forms of horn, are notable for their ability to be heard at great distances. Political borders often split hill peoples between countries, and they are sometimes minorities in their countries with a tradition of resisting control by central government. The Drakensberg are the highest mountain range in Southern Africa, rising up to in height. The people of these mountains are mostly Bantu-speaking people who moved into the area from the north a thousand years ago, displacing the original Khoisan people.
Shipton–Tilman Nanda Devi expeditions
The Shipton–Tilman Nanda Devi expeditions took place in the 1930s. Nanda Devi is a Himalayan mountain in what was then the Garhwal District in northern India, just west of Nepal, and at one time it was thought to be the highest mountain in the world. Nanda Devi is surrounded by a ring of mountains enclosing the Sanctuary which, despite decades of attempts, no one had been able to enter. In 1934 Eric Shipton, Bill Tilman and their three accomplished Sherpas succeeded in finding a climbing route into the Sanctuary via the Rishi Ganga gorge. Then in 1936 Tilman and Noel Odell, as part of an American–British team, climbed to the summit making Nanda Devi the highest mountain ever to have been climbed at that time.
Christian Stangl
Christian Stangl (; born on July 10, 1966 in Landl, Austria) is an Austrian alpine style mountaineer and mountain guide. He has become known as "Skyrunner" by numerous exceptionally fast ascents of high mountains. His major success was in 2013, when he became the first person to ascend the three highest mountains on all seven continents, the so-called "Triple Seven Summits". On January 15, 2013, he was the first person to ascent the "Seven Second Summits", the second highest peaks of all seven continents. On August 23, 2013, after climbing Shkhara (5193m), he became the first person to have reached the third highest peaks on all seven continents.

The summit has been measured in 1999 and 2014, but I don't know the precise value. 
Since then, the height has been measured as in 1999, in 2008, and in 2014.

Precision tests of QED
Quantum electrodynamics (QED), a relativistic quantum field theory of electrodynamics, is among the most stringently tested theories in physics. The most precise and specific tests of QED consist of measurements of the electromagnetic fine structure constant, α, in various physical systems. Checking the consistency of such measurements tests the theory. Tests of a theory are normally carried out by comparing experimental results to theoretical predictions. In QED, there is some subtlety in this comparison, because theoretical predictions require as input an extremely precise value of α, which can only be obtained from another precision QED experiment.
Planck constant
The Planck constant (denoted , also called Planck's constant) is a physical constant that is the quantum of action, central in quantum mechanics. First recognized in 1900 by Max Planck, it was conceived as the proportionality constant between the minimal increment of energy, , of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, , of its associated electromagnetic wave. In 1905, the value , the minimal energy increment of a hypothetical oscillator, was theoretically associated by Albert Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself.
Standard atomic weight
The standard atomic weight ("A", a relative atomic mass) is the atomic weight ("A") of a chemical element, as appearing and met in the earthly environment. It reflects the variance of natural isotopes (and so weight differences) of an element. Values are defined by (restricted to) the IUPAC (CIAAW) definition of natural, stable, terrestrial sources. It is the most common and practical atomic weight used, for example to determine molar mass. The specified definition is to use many representative sources (samples) from the Earth, so that the value can widely be used as 'the' atomic weight for real life substances—for example, in pharmaceuticals and scientific research.
Mount Everest
Mount Everest, known in Nepali as Sagarmāthā and in Tibetan as Chomolungma, is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The international border between China (Tibet Autonomous Region) and Nepal runs across its summit point. The current official height of , recognised by China and Nepal, was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 2005, China remeasured the rock height of the mountain, with a result of 8844.43 m. There followed an argument between China and Nepal as to whether the official height should be the rock height (8,844 m., China) or the snow height (8,848 m., Nepal).
Graduated cylinder
A graduated cylinder, measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. Large graduated cylinders are usually made up of polypropylene for its excellent chemical resistance or polymethylpentene for its transparency, making them lighter and less fragile than glass. Polypropylene (PP) is easy to repeatedly autoclave; however, autoclaving in excess of about (depending on the chemical formulation: typical commercial grade polypropylene melts in excess of ), can warp or damage polypropylene graduated cylinders, affecting accuracy.
Discovery of the neutron
The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics that occurred in the first half of the 20th century. Early in the century, Ernest Rutherford developed a crude model for the atom, based on the gold foil experiment of Hans Geiger and Ernest Marsden. In this model, atoms had their mass and positive electric charge concentrated in a very small nucleus. By 1920 chemical isotopes had been discovered, the atomic masses had been determined to be integer multiples of the mass of the hydrogen atom, and the atomic number had been identified as the charge on the nucleus.
Fine-structure constant
In physics, the fine-structure constant, also known as Sommerfeld's constant, commonly denoted "α" (the Greek letter "alpha"), is a fundamental physical constant characterizing the strength of the electromagnetic interaction between elementary charged particles. It is related to the elementary charge "e", which characterizes the strength of the coupling of an elementary charged particle with the electromagnetic field, by the formula . Being a dimensionless quantity, it has the same numerical value of about in all systems of units. Some equivalent definitions of "α" in terms of other fundamental physical constants are:  where:  The definition reflects the relationship between "α" and the elementary charge "e", which equals .
