243rd blog … vertigo, almagest and plato, naging ptolemy ni tulume kaya naging plato, platito at nagkulang sa pito ang mga tao!

have gone over the rituals in rosemont
jarjeeling the black tea at 1012847 and 036788 but did not win
maybe the very own blend of the bell, like the hole-in-one at de belle, can give me the best cup of all!
really looks like americana! ..

vertigo, a whirling or spinning movement, is a type of dizziness or inappropriate experience of perception of spinning motion, often associated with nausea and vomiting as well as a balance disorder, causing difficulty in standing or walking.

It can be objective when the sensation is as if objects in the environment are moving; it can also be subjective when one feels she/he is the one moving, and the third is known as pseudo vertigo which is an intensive sensation of rotation inside the head …

sa madaling salita, ang vertigo ay liyo o hilo, ang pag-ikot ng mundo sa iyo o ikaw mismo ang umiikot sa mundo na ang dulot ay pagkalula o pagduwal na para kang masusuka dahil bumabaligtad ang sikmura mo …

karaniwang nararamdaman ng mga naglilihi at mga lasenggero’t lasenggera, na parang nilalatigo ng berdugong vertigo ang utak mo, kaya malamang-lamang,  mataas ang high blood pressure mo o napakababa naman ang low blood mo …

cardigan … sa tagalog, pangginaw! a type of knitted garment that has an open front, commonly buttoned but never tied as that would be a robe.

by contrast, a pullover does not open in front but must be “pulled over” the head to be worn. sa tagalog, talukbong o alampay o maski kumot pa.

cardigan was named after the earl of cardigan who led the Charge of the Light Brigade at the Battle of Balaclava during the Crimean War.

modeled after the knitted wool waistcoat that british officers supposedly wore during the war and made popular.

originally, cardigan was a knitted sleeveless vest that turned into other types of garment over time, often worn over shirts and inside suit jackets as a less formal version of the waistcoat or vest that restrains the necktie when the jacket has been removed.

its versatility means it can be worn in casual or formal settings and in any season, but it is most popular during cool weather.

while the almagest is the only surviving comprehensive ancient treatise on astronomy.

babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; greek astronomers such as hipparchus had pro-ptolemy’s cosmos, while in katagalugan, there were the babaylans and the katalunans or “mga haring mago”.

to the almagest, the earth is at the center of the cosmos; the earth, in relation to the distance of the fixed stars, has no appreciable size and must be treated as a mathematical point; and, the earth does not move.

the 16th-century representation of the ptolemy’s geocentric model assigned the order of planetary spheres, beginning with the innermost: moon, mercury, venus, sun, mars, jupiter, and saturn, according to the whims of that time. while plato (c. 427 – c. 347 BC) placed the sun second in order after the moon.

martianus capella (5th century AD) put mercury and venus in motion around the sun, but tolemy’s authority was preferred by most medieval islamic and late medieval european astronomers.

ptolemy inherited from his greek predecessors a geometrical toolbox and a partial set of models for predicting where the planets would appear in the sky.

apollonius of perga (c. 262 – c. 190 BC) had introduced the deferent and epicycle and the eccentric deferent to astronomy.

ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models’ parameters were adopted independently of observations.

the almagest was preserved, like most of classical greek science, in arabic manuscripts (hence its familiar name, then translated twice into latin in the 12th century, once in sicily and again in spain.

ptolemy’s model, like those of his predecessors, was geocentric and was almost universally accepted until the appearance of simpler heliocentric models during the scientific revolution.
