Time Machine: Apollo 14 Successfully Landed on the Moon
February 5, 1971, On this day, Apollo 14 successfully landed near the Fra Mauro crater on the Moon in the Lunar Module. This spacecraft was launched on January 31, 1971. Its mission was to explore the lunar surface and collect samples of rocks and soil available on the Moon. Apollo 14’s remarkable landing marked a pivotal moment in space exploration. As a successor of Apollo 13, this mission not only showcased human resilience but also creativity.
Apollo 14 was commanded by Alan B. Shepard Jr., America’s first man in space. Its crew included Command Module Pilot Stuart A. Roosa and Lunar Module Pilot Edgar D. Mitchell. The journey was not without challenges. On the way, the crew faced docking issues with the Lunar Module, requiring multiple attempts before success. This hurdle tested their skills and underscored the mission’s precarious nature.
Upon landing, Shepard and Mitchell made a moonwalk with extravehicular activities (EVAs), one on February 05 and the other on February 06. They have spent 9 hours, and 23 minutes on the lunar surface. They deployed the Apollo Lunar Surface Experiments Package (ALSEP), conducted geological investigations, and collected approximately 42.28 kilograms of lunar samples.
Golf on the Moon
One of the mission’s iconic moments was Shepard’s impromptu golf session. At the end of the second EVA Shepard used a makeshift club and struck two golf balls, demonstrating the Moon’s low gravity in a memorable way.
While Shepard and Mitchell explored the lunar surface, Roosa remained in lunar orbit aboard the Command Module “Kitty Hawk,” conducting experiments and capturing high-resolution photographs. Notably, On their return journey to the Earth, he carried tree seeds. These seeds were planted across Earth as “Moon Trees”. These trees symbolize the mission’s enduring legacy.
Apollo 14’s success was a testament to human determination and the relentless pursuit of human expertise. It inspires future generations to proudly look at the stars.
Time Machine: Samuel D. Goodale Received Patent For “Stereoscope”
February 5, 1861, On this day, Samuel D. Goodale was granted U.S. Patent No. 31,310 for an invention he termed the “stereoscope”. Later, this device was recognized as the first moving picture peep show machine. This innovative apparatus laid the groundwork for the motion picture industry by creating the illusion of moving images through a sequence of static pictures.
The concept of simulating motion from static images was not entirely new. Earlier inventions, such as the phenakistiscope and the zoetrope, utilized spinning disks or drums with sequential images to create the illusion of movement. However, Goodale’s stereoscope distinguished itself by incorporating stereoscopic images, providing a three-dimensional effect that enhanced the viewer’s experience.
This machine operated by displaying a series of images in rapid succession before a light source, typically a candle. Users would peer through a magnifying lens and manually turn a crank to advance the images. This mechanism produced a semblance of motion, captivating audiences of the era. The device became a popular attraction at fairs and exhibitions, offering viewers a novel form of entertainment.
Goodale’s stereoscope featured a hand-cranked mechanism that moved stereo images past the viewer, a design that would later influence devices like the mutoscope. The mutoscope, popular in the late 19th and early 20th centuries, also used a hand-cranked system to flip through a series of images, offering individual viewers a private moving picture experience.
Evolution of Motion Picture
The significance of Goodale’s invention lies in its contribution to the evolution of motion picture technology. By demonstrating that a sequence of images could create the perception of motion, Goodale’s stereoscope paved the way for future innovations in cinema. It showcased the potential of combining mechanical motion with visual storytelling, a principle that remains fundamental in modern filmmaking.
In retrospect, Samuel Goodale’s 1861 patent represents a pivotal moment in the history of visual entertainment. His moving picture peep show machine not only entertained audiences of his time but also inspired subsequent developments that would lead to the birth of the film industry.

Time Machine: Birthday and Achievements of Sir Alan Lloyd Hodgkin
Born on February 5, 1914, Sir Alan Lloyd Hodgkin was an English physiologist and biophysicist. His fascination with science started early, setting the stage for groundbreaking discoveries in neurophysiology.
Hodgkin, along with Sir Andrew Huxley, conducted groundbreaking research on the ionic mechanisms of nerve cell membranes. Their work explained how electrical impulses travel along neurons. It is a fundamental process in understanding brain and nerve function. They used the giant axon of the squid to demonstrate how sodium (Na⁺) and potassium (K⁺) ions regulate nerve excitation and inhibition, leading to what is now known as the Hodgkin-Huxley Model of nerve conduction.
This discovery laid the foundation for modern neuroscience, influencing treatments for neurological disorders and the development of bioelectronic devices.
For their discoveries about the ionic mechanisms involved in excitation and inhibition in the peripheral and central portions of the nerve cell membrane, Sir John Carew Eccles, Sir Alan Lloyd Hodgkin, and Andrew Fielding Huxley received the Nobel Prize in Physiology or Medicine in 1963.
Their findings remain a cornerstone of medical and biological sciences even today. Hodgkin’s work continues to shape research in neurophysiology, artificial intelligence, and medical advancements. His legacy endures in textbooks, research papers, and the continuous exploration of the human nervous system.
