Worst Bicycle Ergonomics

The worst bicycle ergonomics is surprisingly common. People often ride with their seats too low. This leads to rapid loss of energy, sore muscles and ultimately loss of interest in bicycling.

What is the correct height for your bike seat? You should get almost full extension of your legs at the bottom of the pedaling stroke. Although you normally center the ball of your foot over the axis of the pedal while riding, you can test for proper seat height by leaning against a wall, placing your heels on the pedals, and pedaling slowly backward. Your legs should be just fully extended when your heels are on the pedals.

If it has been a long while since you have ridden and you are somewhat concerned, it is quite OK to set the seat as low as it will go until you are confident again.

Worst Way to Stop a Bicycle

The worst way to stop your bicycle is the way almost everyone does it. They put a foot down on the ground. Instead, you might prefer the ‘invisible kickstand’ trick.

Next time you are waiting at a red light while on your bike, you may want to begin practicing a technique called the ‘track stand.’ As you come to a stop, but before putting a foot on the ground, turn your front wheel about 70 or 80 degrees to the right or left. If your bike is not facing uphill, turn the front wheel facing uphill. This means that your wheel will probably be turned to the left, since most often in non-British countries, the road curves uphill toward the centerline, so that rainwater will run off. Keep steady pressure on one of the pedals, but balance the tendency to roll backward, downhill. With practice, you will find that you can come to a stop and never have to put a foot on the ground. You will be able to rock slightly back and forth, balancing between rolling back and pushing forward.

This trick is used extensively by road racers who don’t want to deal with repositioning a foot on a pedal when it is time to resume riding. For the mountain biker, it helps develop fine control of the bike at slow speeds such as when you are biking along a narrow cliff.

The fellow in the picture above is using a fixed-gear bike (a ‘fixie’) but it can be done on almost any kind of two-wheeled machine. With a fixie, it is not necessary to aim the front wheel uphill.

If you don’t have any slope at all, you can place a hand or foot on the front tire to push the bike backward as needed.

As the guy in the picture illustrates, with practice track stands can be done hands-free.

Worst Bicycling Experience

Some will tell you the worst thing that can happen while riding your bike is being chased by a dog. If that happens, here’s what to do:

1. Slow down or stop. There’s no fun for the dog in chasing something that isn’t moving.

2. In a deep voice, firmly order the dog to “go home.” They often will, but in any case, you’re making it clear who’s in charge and that you do not approve of their current behavior.

3. Get off the bike and place it between you and the dog. It’s a fence to protect you, and if necessary, you can press it against the dog in self-defense.

4. Yell for help. The owner will most likely take control as soon as your plight is discovered.

5. If you encounter the same dog frequently, contact your local animal control agency. In most neighborhoods, it’s illegal to let dogs run loose and bother people.

Worst Oil Change

A student at the University of Santa Cruz, California, was given a new front wheel drive car by her parents. After 1,200 miles, it was due for its first oil change at the dealer, but a fellow student offered to change her oil for free. He figured this would be a good way to get her attention. She reluctantly allowed him to change the oil because it seemed so important to him to do so.

He crawled under the front of the car and removed the transmission drain plug. She commented that the oil seemed awfully thick. He confidently told her that was the way it is supposed to be in new cars. After reinserting the transmission plug, he put four quarts of oil in the engine. Now there was no oil in the transmission and twice as much as there should have been in the engine. She drove a few blocks and the car quit working properly. The dealer towed it away, and after preparing a careful estimate, reported that the damage was not covered by the warranty, being abuse, and repairs would cost almost as much as a whole new car. Her friend got her attention all right!

Worst Lost Airplane Mistake

A B-25 bomber crashed into the 79th floor of the Empire State Building in 1945.

On a foggy Saturday morning in July 1945, a U.S. Army Air Forces B-25 Mitchell bomber lost visibility and crashed directly into the north side of the building between the 78th and 80th floors. Despite structural damage and fires that killed 14 people, the building’s steel frame remained intact, and parts of the building reopened for business two days later.

It holds a Guinness World Record for an elevator survival story. During the 1945 plane crash, elevator operator Betty Lou Oliver survived a catastrophic 75-story drop inside an elevator car after the plane’s engine severed the cables. Cables coiled at the bottom of the shaft and air trapped beneath the car cushioned the fall, making it the highest survived elevator fall in history.

The top of the Empire State Building flexes back and forth a few feet (a meter) in heavy winds.

It was built in just 13 months and completed ahead of schedule. Construction moved at a breakneck pace, progressing at an average rate of four and a half stories per week. Between March 1930 and April 1931, roughly 3,400 workers completed the 102-story structure in just 410 days—finishing under budget and well ahead of schedule.

The original spire was designed as a docking station for dirigibles. The top 200 feet of the building were originally constructed to serve as a mooring mast for commercial airships (Zeppelins). The idea was for airships to tie up to the spire, allowing passengers to disembark via an open-air gangplank on the 102nd floor, but high winds and safety hazards forced the idea to be abandoned after only a couple of brief tests.

It was involved in a fierce “Race to the Sky.” During the late 1920s, developers in Manhattan competed aggressively for the title of the world’s tallest building. The Empire State Building’s designers modified their plans mid-construction—specifically adding the mooring mast—to surpass both 40 Wall Street and the Chrysler Building, securing the crown of world’s tallest building for 41 years until 1972.

It generates more revenue from its observatories than from office rents. While hundreds of businesses lease office space across its lower floors, the 86th and 102nd-floor observation decks consistently bring in more money than commercial real estate leases, generating over $100 million annually from millions of global tourists.

It serves as its own zip code. Due to its massive scale, thousands of daily workers, and high volume of mail, the United States Postal Service assigned the Empire State Building its own unique zip code: 10118.

Its famous tower lights require a dedicated team and change color daily. The building introduced light displays in 1932 to announce Franklin D. Roosevelt’s presidential victory. Today, a state-of-the-art computer-controlled LED system displays over 16 million colors to recognize holidays, sports teams, global organizations, and cultural events.

It is an iconic lightning rod, struck around 25 times per year. Standing tall over Midtown Manhattan, the building’s top spire acts as a massive lightning rod for the city. It features a heavy grounding system that channels millions of volts safely into the earth, preventing structural damage and keeping visitors inside completely safe during storms.

Athletes race up its 1,576 steps in an annual footrace. Every year since 1978, the building hosts the Empire State Building Run-Up. Runners from around the world sprint up the 86 flights of stairs from the ground lobby to the main observatory, with top competitors finishing the vertical climb in under ten minutes.

Worst Computer Bug

Always double-check your work.

The programmer in charge of a computer with the job of issuing traffic citations goofed in September, 1989. The computer sent notices to 41,000 residents of Paris, France informing them that they were charged with murder, prostitution and illegal sale of drugs.

Here’s more about that mistake

What Happened

The Paris judicial system had recently automated its automated notice and collection system. Instead of generating routine notices for minor parking violations and traffic infractions, a bug in the code cross-indexed or misaligned the offense code database.

Rather than pulling the text strings for minor driving infractions (like illegal parking, speeding, or running a red light), the system pulled charges from the severe criminal code database.

The Aftermath

Over 41,000 residents opened official, sternly worded legal summonses from the Ministry of Justice informing them that they were under investigation or charged with major crimes—including:

Murder and manslaughter

Organized prostitution

Extortion and blackmail

Illicit drug trafficking

As you can imagine, the mistake caused widespread panic, outrage, and chaos at local police stations and court houses as thousands of bewildered drivers showed up trying to clear their names of hitman-level charges when they had simply overstayed a parking meter.

French officials quickly issued public apologies, clarified that it was a technical glich, and assured residents that no felony charges were actually being pursued. It remains a legendary classic example in computer science and IT history of what can go wrong with early automated database management.

Worst Submarine

The world’s worst submarine was the first submarine. That makes sense. It had very limited capabilities. In it’s one and only attempted attack it was comically ineffective.

In the mid 1770’s David Bushnell, an inventive guy, created the world’s first attack submarine. Using whiskey barrel technology, he made a watertight clam shell shaped vehicle with barely enough room for one man. The thing, nicknamed the Turtle, was placed in New York Harbor one night Continue reading Worst Submarine

Worst Lost Opportunity

Volkswagenwerkes, Germany

After World War II, Henry Ford was offered the Volkswagen factory for free by the English government, then in charge of Germany’s industries. They were looking for someone who could operate the plant, thereby creating hundreds of jobs. Ernest Breech, Ford’s chairman of the board looked the plant over and said, “Mr. Ford, I don’t think what we are being offered here is worth a damn!”

He was right in a way. At that time Continue reading Worst Lost Opportunity
