The controversy between Thomas Edison and Nikola Tesla is one of the most famous rivalries in the history of science and technology, often referred to as the "War of the Currents.”
**Thomas Edison** was a leading inventor and businessman, best known for developing the practical incandescent light bulb and direct current (DC) electricity distribution systems. Edison believed in the potential of DC and heavily invested in promoting it as the standard for electrical power distribution.
**Nikola Tesla**, a Serbian-American inventor and engineer, once worked for Edison but later became one of his fiercest competitors. Tesla developed the alternating current (AC) system, which he believed was more efficient for transmitting electricity over long distances. AC could be transformed to higher or lower voltages with the use of transformers, making it more practical and cost-effective for widespread use.
The conflict between the two became particularly intense in the late 1880s, with Edison aggressively promoting DC as safer and less prone to accidents. He went as far as to demonstrate the dangers of AC by publicly electrocuting animals and even supporting the development of the electric chair, which used AC, to associate it with death and danger.
Despite Edison’s efforts, AC eventually won out. Tesla's AC system, backed by industrialist George Westinghouse, proved to be more efficient and practical for powering cities. The 1893 World's Columbian Exposition in Chicago was a turning point, where Tesla and Westinghouse used AC to power the entire fair, showcasing its superiority.
Ultimately, Tesla's AC system became the standard for electrical power distribution worldwide, while Edison’s DC system was largely phased out for long-distance power transmission. The rivalry highlights the intense competition in the early days of electricity, where the battle between innovation and public perception played a critical role in shaping the future of technology.

This is 280lbs. So what’s the history of women in lifting??: The history of women in weightlifting has evolved significantly over the years.
Early 20th Century **1900s-1930s**: Weightlifting was largely a male-dominated sport. Women rarely participated in strength sports, and societal norms discouraged women from engaging in such activities.
### Mid 20th Century **1940s-1960s**: During and after World War II, women began to enter various sports, including weightlifting, as they took on more roles traditionally held by men. However, organized weightlifting competitions for women were still scarce.
### Late 20th Century **1970s-1980s**: The feminist movement and increased awareness of gender equality led to more opportunities for women in sports. In 1983, the first Women's World Weightlifting Championships were held. **1990s**: Women's weightlifting continued to grow in popularity and recognition. The International Weightlifting Federation (IWF) formally included women's events, and women competed in their first Olympic Games in 2000 in Sydney.
### 21st Century **2000s-Present**: Women's weightlifting has become mainstream, with female athletes breaking records and gaining visibility. Women now compete at all levels, from amateur to professional, and participate in major competitions like the Olympics, World Championships, and various regional contests.
### Notable Figures **Abbye "Pudgy" Stockton**: A pioneer in women's strength training and weightlifting during the 1940s. **Karyn Marshall and Judy Glenney**: Early champions who helped pave the way for women's competitive weightlifting. **Liao Qiuyun and Tatiana Kashirina**: Modern-day weightlifters who have set world records and achieved significant success on the global stage.
The journey of women in weightlifting reflects broader social changes and the fight for gender equality in sports and society.
After dinner 😁🫠 So what’s the history of dinner ??? : The concept of dinner has evolved significantly over time, influenced by cultural, social, and economic changes.
**Ancient Times**: In ancient civilizations like Egypt, Greece, and Rome, the main meal of the day was typically eaten in the late afternoon or evening. In Rome, for example, the "cena" was the main meal, often elaborate and social, held in the late afternoon or early evening.
**Middle Ages**: In medieval Europe, dinner was originally eaten around midday, with a lighter supper in the evening. This was due to the lack of artificial lighting, making it practical to have the main meal while it was still light.
**Renaissance to Early Modern Period**: By the 16th and 17th centuries, dinner began to shift later in the day. Among the wealthy, it was often a social event with multiple courses, reflecting the increasing availability of a variety of foods and spices.
**18th to 19th Century**: The Industrial Revolution brought changes to daily schedules, pushing dinner later into the evening. In Britain and America, the working class often had their main meal after work, while the upper class maintained later, elaborate dinners.
**20th Century to Present**: Today, dinner time varies widely by culture and lifestyle. In many Western countries, dinner is typically eaten in the early evening. However, in Mediterranean countries like Spain and Italy, dinner is often eaten much later, around 9 or 10 PM. The meal can range from a simple, quick meal to a more elaborate, social event.
Throughout history, dinner has remained a central aspect of daily life, reflecting broader societal changes and serving as a time for family and social gatherings.
