The Linear Belt And The Inclined Elevator
- Jesse Reno, an engineer, worked in a Subway plan for New York City, and proposed a ‘linear belt’ to move passengers, which later morphed into an ‘Inclined Elevator’, which was a huge success, and was installed in the Brooklyn Bridge in 1897.
- George Wheeler, another inventor, created the concept of the Escalator that we know today, and called it the Elevator, the patents were purchased for the same by Charles Seeberger, who partnered with OTIS to create the Escalator, a trademarked product.

The cheap pen that changed writing forever
A replacement for fountain pens
Fountain pens, although stylish, were messy and impractical.
In 1945, Gimbels started to sell a new kind of ink pen, made by the Reynolds International Pen Company. With its quick-dry ink a...
Combining functionality with affordability
The first generation of ballpoint pens cost around 55 shillings (£82.50/$107.50 in 2020 prices). It was in the same style as fountain pens. They were made of metal and intended to be refilled with ink. But with so many companies selling it, the market became saturated, buying refills, but not more pens.
Italian-born French industrialist Michel Bich added the catalyst of disposability. He understood the concept of the mass market and created his new company, Societe Bic. His pen only cost a shilling.
The ballpoint pen transforming societies
The ballpoint pen was the equivalent of today's smartphone. Before the ballpoint pen, writing was a stationary act that had to be done on a certain kind of desk, with all the other things at hand that allowed you to write.
The ballpoint pen turned writing into something that could happen anywhere. Plastic mass production allowed the pens to become even cheaper, allowing for the transformation of societies.

Incidental physical activities
Are physical activities undertaken as part of carrying out normal daily chores.
Brief sessions of 20 seconds of stair-climbing (60 steps) repeated 3 times a day on 3 days per week over 6 weeks for example can lead to measurable improvements in cardiorespiratory fitness.
Incorporating incidental physical activity into our routines
- Replace short car trips with fast walking, or cycling;
- Walk up the stairs at a fast pace instead of using the elevator;
- Vigorous walk at a pace of about 130-140 steps per minute;
- Look for opportunities to walk uphill;
- Take your dog to an off-leash area and jog for 30-90 seconds alongside the pup.

How bicycles transformed our world
Bicycles
Invented back in the 19th century, bicycles were as disruptive as the iPhone was when it was launched in 2007.
A bicycle was unbelievably cool, took one anywhere for free quickly and didn’t...
The Invention of The Bicycle
John Kemp Starley invented the bicycle as we know it today when he was only 30. His ‘Rover Safety’ bicycle, first displayed in a bicycle show in 1886, was a curiosity, but later when pneumatic tires were added to it to cushion the ride, it became safer, smoother and also 30 per cent faster.
Women Power and Bicycles
The masses, especially women, suddenly experienced freedom to go anywhere without the need for expensive carriages and horses.
The bicycles transformed society, and emancipated women in a way nothing else could. Women found them lightweight, fast, affordable and easy to take care of.
