Jackie Mitchell was one of the first female pitchers in professional baseball history. Pitching for the Chattanooga Lookouts Class AA minor league baseball team in an exhibition game against the New York Yankees, she struck out Babe Ruth and Lou Gehrig in succession. She is shaking hands with both of them in this picture.

IBM 350 disk storage unit
In 1956, IBM introduced the 305 RAMAC system, generally acknowledged as the first (commercially successful) computer to feature what we would now call a “disk drive” or “hard drive” (i.e., data stored on a magnetic disk and accessed via a moving head). What is pictured above is the IBM 350 disk storage unit utilized by the IBM 305 RAMAC.
Introduced in 1956, the IBM 305 RAMAC (Random Access Memory Accounting System) was an electronic general purpose data processing machine that maintained business records on a real-time basis. The 305 RAMAC was one of the last vacuum tube systems designed by IBM, and more than 1,000 of them were built before production ended in 1961.”
The 305 was a flexible, electronic, general purpose data processing machine that enabled businesses to record transactions as they occurred and concurrently reflect each entry in affected accounts. It maintained records on a real-time basis, provided random access to any record, eliminated peak loads, and could simultaneously produce output by either print or punched cards.
The 305 system consisted of the IBM 305 Processing Unit (containing the magnetic process drum, magnetic core register and electronic logical and arithmetic circuits), the IBM 370 Printer (an 80-position serial-output printer with tape control carriage), the IBM 323 Card Punch (similar to the IBM 523 Gang Summary Punch, providing for 80 columns of output punching), the IBM 380 Console (containing the card feed, typewriter, keyboard and indicator lights and control keys), the IBM 340 Power Supply (supplying power for all components except the motors in the 350 disk storage unit), a utility table adjacent to the console, and the IBM 350 Disk Storage Unit.
The 350 Disk Storage Unit consisted of the magnetic disk memory unit with its access mechanism, the electronic and pneumatic controls for the access mechanism, and a small air compressor. Assembled with covers, the 350 was 60 inches long, 68 inches high and 29 inches deep. It was configured with 50 magnetic disks containing 50,000 sectors, each of which held 100 alphanumeric characters, for a capacity of 5 million characters.
Disks rotated at 1,200 rpm, tracks (20 to the inch) were recorded at up to 100 bits per inch, and typical head-to-disk spacing was 800 microinches. The execution of a “seek” instruction positioned a read-write head to the track that contained the desired sector and selected the sector for a later read or write operation. Seek time averaged about 600 milliseconds.
In 1958, the 305 system was enhanced to permit an optional additional 350 Disk Storage Unit, thereby doubling storage capacity; and an additional access arm for each 350.

Early morning train in Japan, 1964
The custom of facemask-wearing began in Japan during the early years of the 20th century, when a massive pandemic of influenza killed between 20 and 40 million people around the world—more than died in World War I. There were outbreaks of the disease on every inhabited continent, including Asia (where it devastated India, leading to the deaths of a full 5% of the population). Covering the face with scarves, veils and masks became a prevalent (if ineffective) means of warding off the disease in many parts of the world, until the epidemic finally faded at the end of 1919.
In Japan, a few years later, the Great Kanto Earthquake of 1923, triggered a massive inferno that consumed nearly 600,000 homes in the most populous part of the nation. After the quake, the sky was filled with smoke and ash for weeks, and air quality suffered for months afterward. Facemasks came out of storage and became a typical accessory on the streets of Tokyo and Yokohama. A second global flu epidemic in 1934 cemented Japan’s love affair with the facemask, which began to be worn with regularity during the winter months—primarily, given Japan’s obsession with social courtesy, by cough-and-cold victims seeking to avoid transmitting their germs to others, rather than healthy people looking to prevent the onset of illness.
Does it even help with anything? Yes. A 2008 study published in the International Journal of Infectious Disease concluded that when used correctly, masks are highly effective in preventing the spread of infections. Family members of children with flu-like illnesses who used the masks properly were 80 percent less likely to be diagnosed with the illness. The difference between types of masks used was insignificant (MacIntyre, 2008).
A utility worker attempts mouth-to-mouth resuscitation on a co-worker after he accidentally touched a high voltage wire (1967).
Taken in 1967 by Rocco Morabito, this photo called “The Kiss of Life” shows a utility worker named J.D. Thompson giving mouth-to-mouth to co-worker Randall G. Champion after he went unconscious following contact with a Low Voltage line. They had been performing routine maintenance when Champion brushed one of the low voltage lines at the very top of the utility pole. His safety harness prevented a fall, and Thompson, who had been ascending below him, quickly reached him and performed mouth-to-mouth resuscitation. He was unable to perform CPR given the circumstances, but continued breathing into Champion’s lungs until he felt a slight pulse, then unbuckled his harness and descended with him on his shoulder. Thompson and another worker administered CPR on the ground, and Champion was moderately revived by the time paramedics arrived, eventually making a full recovery.
What’s even more incredible is Champion not only survived this thanks to Thompson, but he lived an extra 35 years. He died in 2002 at 64 years old. Thompson is still alive today.
Morabito was driving on West 26th Street in July 1967 on another assignment when he saw Champion dangling from the pole. He called an ambulance and grabbed his camera. “I passed these men working and went on to my assignment,” says Morabito. “I took eight pictures at the strike. I thought I’d go back and see if I could find another picture.” But when Morabito gets back to the linemen, “I heard screaming. I looked up and I saw this man hanging down. Oh my God. I didn’t know what to do. I took a picture right quick. J.D. Thompson was running toward the pole. I went to my car and called an ambulance. I got back to the pole and J.D. was breathing into Champion. I backed off, way off until I hit a house and I couldn’t go any farther. I took another picture. Then I heard Thompson shouting down: He’s breathing!”
Rocco Morabito won the 1968 Pulitzer Prize for Spot Photography for this photograph, called “The Kiss of Life.”
- Today mouth-to-mouth resuscitation is unnecessary and American Heart Association (AHA) don’t recommend using it anymore. One of the big factors in the AHA’s decision to lessen the importance of ventilation in the newest resuscitation guidelines, was to make it easier and more likely for bystanders to actually perform CPR. The studies showed that many people would not perform CPR on a stranger because of the mouth-to-mouth part. By reducing the importance, they hope that more people will perform chest compressions, which by themselves can be very effective.
- The lines above are Low Voltage (50-1000 Volts) and not High Voltage (HV). The worker is working on a transformer. In order to work on the HV part of a transformer, you need an Access Permit (name may change with countries), a document following a strict set of procedures to turn the power off. A High Voltage flash causes massive burns and a huge fireball. The clothes burn away to nothing and hair is burnt off.
- In the industry, there is no rescue procedure for HV shock, because by the time it takes to turn the power off to safely retrieve the victim, they are already burned. Their best chance is if they are blown off the pole from the explosion and treated right then.
Schwerer Gustav was the name of a German 80 cm (31.5 in.) railway gun. It was developed in the late 1930s by Krupp as siege artillery for the explicit purpose of destroying the main forts of the French Maginot Line, the strongest fortifications then in existence. The fully assembled gun weighed nearly 1,350 tonnes, and could fire shells weighing seven tonnes to a range of 47 kilometres (29 mi). It was the largest-calibre rifled weapon ever used in combat, the heaviest mobile artillery piece ever built in terms of overall weight, and fired the heaviest shells of any artillery piece. It is only surpassed in calibre by the British Mallet’s Mortar and the American Little David mortar (both 36 inch; 914 mm).
