Maryam Al-IjliyaShe lived in the tenth century in Aleppo, Syria and was a famous scientist who designed and constructed astrolabes. Astrolabes were global positioning instruments that determine the position of the sun and planets, so they were used in the fields of astronomy, astrology and horoscopes.Her hand-crafted designs were so intricate and innovative that she was employed by the ruler of the city, Sayf Al Dawla, from 944 AD until 967 AD. She will always be remembered in history for her genius designs.

According to Wikipedia olive oil has a specific gravity at 293 K of 911 kg/m, and at first glance that looks like a serious problem for any swimmer.So that's approx 91% of the density of water, giving 91% of the buoyant force to counter gravity. And it looks like depending on body mass and lung capacity in use, the density of the human body can range from 944 to 1010 kg per cubic meter.This means that swimming actions are only providing 91% of the thrust that they did in water. You're going to have to stroke/kick harder and faster than you did in water in order to stay afloat and/or make forward progress.It isn’t advisable, but yes, it is possible.

The word alchemy in turn is derived from the Arabic word al-kīmīā (الکیمیاء) even tho the discipline of chemistry began with experiments in the mystical field of alchemy, yet it was only towards the end of 9th century that scientific breakthroughs were to be realized, thanks to a few brilliant Arab Muslim scholars who transformed the mystical and unreliable science of alchemy into the rigorous science of chemistry.Precise observations and controlled experiments by these Muslim chemists led to the development of many new tools, processes and classifications, opening the door to new industry and invention and great advances in pharmacology.These groundbreaking scientists laid the foundation for modern chemistry and informed the work of many other scholars for centuries to come.In Chemical processes and laboratoriesJabir ibn Hayyan was the first person to perfect the alembic still and many chemistry processes such as distillation, crystallization, sublimation, oxidation and evaporation.He also set up the first modern laboratory and developed many new chemistry techniques and tools, such as the crucible, cucurbit and the distillation retort.Banu Musa Brothers (d. 873) were known for their amazing trick devices, the three brothers, Muhammad, Ahmad and al-Hasan, were great mathematicians, translators and creators of trick devices. Their most notable work is their ‘Book of Ingenious Devices’ that details over 100 trick devices that they designed.Al-Jazri who built the world First Programmable Humanoid Robot, it was a mechanical peacock that was controlled and moved through hydraulic pressure.He designed and built a number of automates, he pioneered advances in robotics and credited with inventing camshaft, crank-shank, and segmental gearing which are presented in almost every machine today.Mariam Al-Ijliya She was a 10th century schooler in Aleppo who pioneered , designed and developed astrolabes a medieval device that was the GPS of its day they were used in the fields of astronomy, astrology and horoscopes. She was a student of a certain Bitolus, who was a well known manufacturer of astrolabes in Baghdad and she in turn became his student. Her hand-crafted designs were so intricate and innovative that she was employed by the ruler of the city, Sayf Al Dawla, from 944 AD until 967 AD.Ibn Al Haytham also known as Al-Hazen (965-1040 CE) He was the first theoretical physicist that's why he is referred as the first scientist, he has been the earliest to discover that a hypothesis has the necessity to be experimented through confirmable procedures or mathematical evidence, hence developing the scientific method 200 years before it was approved by Renaissance scientists. He was the first scientist to realize that when a tiny hole is put onto the side of a lightproof box, rays of light from the outside are projected through that pinhole into the box and onto the back wall of it.Ibn al-Haytham’s discoveries regarding cameras and how to project and capture images led to the modern development of cameras around the same concepts. Without his research into how light travels through apertures and is projected by them, the modern mechanisms inside everyone’s cameras would not exist.Al-Zahrawi was credited to be the first to describe ectopic pregnancy he also was the first to illustrate the various cannulae and the first to treat a wart with an iron tube and caustic metal as a boring instrument. He was also the first to draw hooks with a double tip for use in surgery.He was also the first to describe a surgical procedure for ligating the temporal artery for migraine, also almost 600 years before Pare recorded that he had ligated his own temporal artery for headache that conforms to current descriptions of migraine.Al-Zahrawi was therefore the first to describe the migraine surgery procedure that is enjoying a revival in the 21st century,He introduced over 200 surgical instruments , any of these #instruments were never used before by any previous surgeons.He was the greatest medical surgeon in that era, For over five hundred years, his encyclopaedia of sturgery was used as a standard reference work in the subject in all universities of Europe.Al-Zahrawi specialized in curing disease by cauterization. He invented several devices used during surgery, such as inspection of the interior of the urethra, applying and removing foreign bodies from the throat, inspection of the ear, etc.Alexander Von Humboldt says on his book of science:"It was the Arabs who for the first time invented the method of chemical preparation of medicines, and it was from this sound advice and the procedure of experiments of medicine and natural elements came to us, and thus the door on a new era of the study of this science was opened by the Arabs.Suffice it for the proof of the vast Arab knowledge of the plant kingdom that they made addition of two thousand herbs to those Zulefuredas.There were many herbs in their pharmacy that the Greeks had not even dreamt of."
