It was likely made by early humans using grains mixed with water or milk and cooked over fire. Ancient civilizations such as the Greeks and Romans also enjoyed porridge-like dishes, but pinpointing a specific inventor is difficult due to its long history and widespread variations.

To use a sundial today, place it in a sunny location where it won’t be obstructed. Align the gnomon (the part that casts the shadow) with true north to ensure accurate timekeeping. As the sun moves, the shadow cast by the gnomon will indicate the time on the hour lines marked on the sundial's face. Remember, sundials typically show solar time, which may differ from standard clock time due to factors like the equation of time and daylight saving adjustments.

W.B. Purvis, an African American inventor known for his work in the late 19th century, was born to parents who were formerly enslaved. His father, a skilled carpenter, and his mother, a homemaker, played significant roles in shaping his early life and education. However, specific details about their names and backgrounds are not widely documented.

The U.S. blacksmith who invented the steel plow in 1837 was John Deere. His innovative design helped transform agriculture by making it easier to till the tough, sticky soil of the Midwest. Deere's steel plow was more durable and efficient than previous wooden models, significantly aiding in the expansion of farming in the region. His invention laid the groundwork for the modern agricultural industry.

Three common items made of rubber include tires, which provide traction and durability for vehicles; erasers, used for correcting mistakes on paper; and rubber bands, which are used for bundling items together. Rubber's flexibility and resilience make it ideal for these applications. Additionally, rubber is often found in various types of footwear, such as sneakers and rain boots.

The first carriages, often referred to as "chariots," were typically two-wheeled vehicles pulled by horses. They featured a simple design with a wooden frame and a seat for one or two passengers. Chariots had open sides and were used for both transportation and military purposes, with some adorned with decorative elements. Over time, carriages evolved to include four wheels, enclosures, and more elaborate designs for comfort and style.

The Doctrine of Lapse was introduced by Lord Dalhousie, the British Governor-General of India, in the mid-19th century. This policy allowed the British East India Company to annex any princely state if the ruler died without a male heir, thereby expanding British control over Indian territories. The doctrine played a significant role in the annexation of several states and contributed to growing resentment towards British rule, ultimately leading to the Indian Rebellion of 1857.

The first-ever broadcasted programs were primarily experimental radio transmissions in the early 20th century. One notable early broadcast was by Canadian inventor Reginald Fessenden in 1906, where he transmitted voice and music on Christmas Eve. In the realm of television, the first public demonstration occurred in 1927 by Philo Farnsworth, while the first regular television broadcasts began in the late 1930s, with programs like "The Queen's Messenger" being among the first. These early broadcasts laid the groundwork for the development of modern radio and television.

The invention of airmail revolutionized communication in America by significantly reducing the time it took for letters and packages to be delivered, fostering greater connectivity across the country. This expedited service made it easier for businesses to operate nationwide, enhancing commerce and trade. Additionally, airmail facilitated personal connections, allowing families and friends to communicate more frequently and reliably, thus strengthening social ties. Overall, it contributed to a more interconnected and efficient society.

Jack Grant invented the inflatable aircraft escape slide and raft to enhance passenger safety during emergencies. Recognizing the need for an efficient and rapid evacuation method from aircraft, he aimed to provide a quick and reliable means for passengers to exit safely in the event of an emergency landing or crash. His innovation significantly improved the overall safety standards in aviation, ensuring that passengers could evacuate swiftly and effectively.

Before airplanes were invented, people relied on various forms of transportation for long-distance travel, including trains, ships, and horse-drawn carriages. The advent of steamships and railroads in the 19th century significantly accelerated travel times across continents. Additionally, hot air balloons and airships were experimented with for aerial travel, albeit with limited success and safety. Overall, travel was generally slower and more labor-intensive compared to modern air travel.

The thermos bottle was invented in 1892 by Scottish scientist Sir James Dewar. He developed it as a vacuum flask to store liquefied gases, utilizing the principle of reducing heat transfer. The design was later commercialized in 1904, leading to the creation of the well-known brand Thermos. This innovation revolutionized how beverages could be stored and kept at desired temperatures.

The last single-digit number invented is often considered to be 9, as it is the highest number in the base-10 (decimal) system that we commonly use. However, it's important to note that numbers aren't "invented" in the traditional sense; they are discovered and represented by various cultures throughout history. In modern mathematics, the concept of numbers extends beyond single digits to include zero and negative numbers, expanding our understanding beyond just single digits.

The exact inventor of fluffy socks is not clearly documented, as they evolved over time as a type of knitted or woven sock designed for comfort and warmth. Fluffy socks became popular in the late 20th century, particularly with the rise of cozy homewear trends. Various manufacturers and brands have contributed to their popularity, but no single person is credited with their invention.

Fingerprinting, while widely used for identification and security, poses several risks. One major concern is privacy; unauthorized access to fingerprint data can lead to identity theft or misuse. Additionally, biometric systems can be vulnerable to spoofing or hacking, where artificial fingerprints are created to bypass security measures. Lastly, if a fingerprint database is compromised, individuals may be permanently at risk, as unlike passwords, fingerprints cannot be changed.

Robert Fulton died in New York City on February 24, 1815. He was an American engineer and inventor best known for developing the first commercially successful steamboat, the Clermont. Fulton's innovations in transportation significantly impacted the development of waterways and commerce in the United States.

This was the first successful transatlantic telegraph cable, enabling instant communication between North America and Europe. The project marked a significant technological advancement in global communication.

The prominent American balloonist of the mid-nineteenth century was John Wise. He gained fame for his extensive ballooning adventures and made significant contributions to the field of aeronautics. Wise was known for his daring ascents and was involved in various ballooning experiments, including attempts at long-distance flights. His work helped popularize ballooning in the United States during that era.

Before the invention of formal number systems, people used various methods to count, often relying on physical objects or tally marks. They might use their fingers, stones, or notches on sticks or bones to represent quantities. Additionally, many cultures employed simple counting systems based on grouping items, such as counting by twos or fives, which helped them keep track of larger amounts without needing formal numbers. These methods provided a practical way to manage everyday tasks and resources.

A mechanical fastener is a hardware device used to join two or more components together securely. Common types include screws, bolts, nuts, and rivets, which create a physical connection by interlocking or clamping parts. Fasteners can be temporary or permanent and are widely used in various industries, including construction, automotive, and manufacturing, to ensure structural integrity. They are essential for assembly processes and can be made from various materials, such as metal, plastic, or composite materials.
