5 science innovations that changed the world!

Retro Delight: Science & Technology

Fasten your seat belts everyone! Time for a science field trip to The Magical days of the older decades!

The clunky technology of the ’20s to 90s paved the way for innovations in today’s classrooms. It was an era where there was prestige involved in walking up to the board and write on the chalkboard. However, growing up in that time seems like an adventure to all those who are addicted to fancy gadgets and tools developed from this technology.

Children today would scratch their heads at a floppy disk. And who would know what to do without Google?

To celebrate technology of the past, that laid the foundation of new gadgets, advancing technologies and fancier tools, we have compiled a list of science tools used back in the day even before the existence of the internet!

So buckle up for the blast from the past, because it’s time to ford the river down memory lane.

1. The Computer that Got us on the Moon

‘Apollo guidance Computer’  had a 16-bit word length, with 15 data bits and one parity bit. The iPhone is so advanced compared to the computer used in Apollo’s guidance system that it’s hard to believe they both came from the same planet.

2. Beginning of Networking

The beginning of networking was laid with ‘news wire services’ in the 1920s, they used multiplex devices that satisfied the definition of a modem, the first commercial modem, specifically for converting digital computer data to analog signals for transmission across its long distance network.

Its top transmission speed was able to transmit punched cards at 25 bits/second, slower than half of what we use today!

3. X-rays that changed the course of diagnosis

The emergence of CT scan would not have been possible if not for the discovery of X-rays by Roentgen in 1895.

4. The magic of microscopes

light microscope developed in 1800s with an aperture of 1.4 has accordingly a maximal useful magnification of 1400 fold. This revealed the cellular structure of almost all living organisms of the plant as well as animal kingdom

5. The Electronic Calculator

The electronic calculators of the mid-1960s were large and heavy desktop machines due to their use of hundreds of transistors on several circuit boards with a large power consumption that required an AC power supply with only square root function.

And today, even for simple addition- subtraction we need calculators. For geeks like us, scientific calculators are always kept handy.

Besides being grateful for the discovery of the first internet game ‘space-war’ have you imagined where will science and technology be in a decade from now? Edward Teller has rightly said, “The science of today is technology of tomorrow.”

As you bow your head in gratitude towards science, secretly hoping that you get to contribute to these discoveries, here’s a nod to the most breathtaking — advances in science on our platform! (http://functionspace.org/)

Love science, share science!
