People and the surroundings in the earth are always inter-relatable to each other, and human technologies have grown to great heights. Contemporary devices and tools of development have attained uses in more than unimaginable way! But the core starting point or the stage of beginning also should be entitled to appreciation, since ideas grew from there! Therefore, let us travel through the retro times in the technology!
1. STEAM ENGINE
Heron Alexandrinus takes the whole credit for inventing the first steam engine. His steam device was called by the name of the god of wind, as Aeolipile. The two nozzles attached to a round globe-like sphere will make it rotate giving torque and producing steam! The steam results from the boiling water inside the globe.
2. STORAGE OF ICE
Yakhchal, the ice pit which is 60 feet formed by the Persian people to store the ice brought from nearby places, is a large storage pit in the center of a desert! Yakhchal is the first ancient refrigerator known to humankind.
3. ARCHIMEDES SCREW
Irrigation in ancient medieval eras was primarily made possible by the use of a machine which is an actual screw pipe. A rotating helicoid with the help of gravity will travel upwards inside water.
4. RAMPS FOR CONSTRUCTION
Egyptian people are always well-known for their amazing brainy powers of technological advancements. Egyptians were able to build tall domes and pyramids with the help of ramps. Ramps were useful for carrying the construction goods and materials, and applying light force for longer distanced made it possible for Egyptians to be well knowledgeable!
5. NIMRUD LENS
The Nimrud lens was possibly the first ever telescope in 1608 A.D found on earth by Sir John Layard in modern day Iraq. It is an oval rock-crystal with a focal length of 11 centimeters and magnifying capacity of 3 X.
The first calendar was identified by in Scotland in 2004 site excavations. The sophisticated system was found to be 10,000 years old. The timetable is present with 50 meters of long lines with 12 separate pits from Stone Age; the depths represent the months for the whole year and every month was separated as ten days in a week!
7. EARTHQUAKE DETECTOR
The first ever detector for earthquakes was significant to the Chinese astronomer, mathematician and the engineer Zhang Heng. His seismoscope was a big vessel of bronze 6 feet in diameter. Eight snake-dragons were present beneath to detect the direction! The seismoscope depicted things correctly at the olden time itself.
8. ANCIENT NAVIGATIONAL DEVICE
A Norse found a thing that could detect the seas based upon the sun even when it is hidden behind the clouds. The March 2016 excavation findings suggest that the calcite crystal identified in the wreck of an Elizabethan ship was a real shard that is similar to Viking’s and is useful for navigation.
9. BAGHDAD BATTERY
The Baghdad battery, clay pot which has a small copper container inside of it with an iron rod supportive by an asphalt plug, is an electric battery that was present in 250 B.C. Latest reports suggest that the device could give a 2V electric current from it!
The first ever wheel useful for pottery way by the Mesopotamians around 3500 B.C. later after three hundred years, then it was fixed under king’s chariots, and now we have the highly technical wheels for even big container trucks!
