فارادی به بررسی میدان مغناطیسی اطراف یک رسانا که از آن جریان مستقیم می‌گذرد پرداخت و نخستین مفاهیم میدان الکترومغناطیسی را در فیزیک بنیان نهاد. وی القای الکترومغناطیسی و برق‌کافت (الکترولیز) را کشف کرد. او همچنین ثابت کرد که میدان مغناطیسی بر پرتو نور اثر می‌گذارد و رابطه‌ای اساسی بین این دو برقرار است. اختراعات او در زمینه دستگاه‌های چرخان الکترومغناطیسی، فناوری موتور الکتریکی را پی ریخت، و در اثر تلاش‌های او بود که الکتریسیته در فناوری کاربرد یافت.

با این‌که فارادی تحصیلات رسمی اندکی داشت و تنها کمی ریاضیات، مانند حساب دیفرانسیل و انتگرال، می‌دانست، یکی از اثرگذارترین دانشمندان تاریخ بود. برخی از مورخان علم او را بزرگ‌ترین تجربه‌گر در تاریخ علم می‌دانند.فاراد که واحد ظرفیت الکتریکی در سیستم SI است به افتخار او نامیده شد، و نیز ثابت فارادی، که بار الکتریکی یک مول الکترون است (حدود ۹۶٬۴۸۵ کولن). بر پایهٔ قانون القای فارادی، اگر میدان مغناطیسی با زمان تغییر کند، نیروی محرکه الکتریکی تولید می‌کند.

وی از نیروی بخار در حرکت لکوموتیو استفاده کرد و این وسیله نقلیه معتبر را به وجود آورد، وی از راه‌های گوناگون از جمله کارگری معدن، رانندگی و گاوچرانی و شاگرد شوفری مخارج زندگی خود را تأمین می‌کرد و مدت ۱۵ سال برای اختراع لوکوموتیو زحمت کشید و سرانجام این غول آهنی را به حرکت درآورد. چنانچه جورج استیفنسن در بخش یک کان زغال‌سنگ واقع در شمال انگلیس به دنیا نمی‌آمد، شاید هرگز به فکر اختراع لوکوموتیو و قطار راه آهن نمی‌افتاد؛ زیرا او بخاطر اینکه زغال‌سنگ به راحتی از معدن زغال‌سنگ بایک وسیله راحت نقل مکان شود، به فکر اختراع لوکوموتیو و بعد هم واگن راه آهن افتاد.

Google was founded on September 4, 1998, by Larry Page and Sergey Brin while they were PhD students at Stanford University in California. Together they own about 14% of its publicly listed shares and control 56% of its stockholder voting power through super-voting stock. The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc. Google is Alphabet's largest subsidiary and is a holding company for Alphabet's Internet properties and interests. Sundar Pichai was appointed CEO of Google on October 24, 2015, replacing Larry Page, who became the CEO of Alphabet. On December 3, 2019, Pichai also became the CEO of Alphabet.

Steve Jobs. The iconic American entrepreneur and founder of Apple will go down in history as one of the great innovators. As CEO of Apple in the 1980s and again in the late 90s and 2000s, Jobs played a central role in the personal computer revolution and in developing its key products, including the McIntosh, the iPod and the iPhone.

A full list of Beulah Louise Henry's inventions would be a lengthy one — she's known for 110 inventions and 49 patents, and the American inventor profited from all of them. Henry submitted her first patent, for a vacuum ice cream freezer, while still a college student in 1912, and moved to New York City in 1924 to found two companies to sell her many inventions. In the 1930s and 1940s, she shifted her attention to improving existing machines, including typewriters; one of her patents, for a "protograph," was a typewriter that created and original and four identical copies without carbon paper. With her reputation as a professional inventor solidified, she spent the 1950s and part of the 1960s working for companies as a consultant, and when she died in 1973 she was remembered by all for her creativity and drive. Henry, however, would have argued that she didn't need drive to create so many inventions: "I invent," she said, "because I cannot help it."

Can you imagine driving a car in bad weather without windshield wipers? Until Mary Anderson thought of them, that was the only option! Anderson was already a real estate developer and rancher when she visited New York City in 1902 and rode on a trolley car where the driver had to open the panes of the front window in order to see through falling sleet. As soon as she returned home to Alabama, she set to work conceiving a solution. Her device used a lever inside the vehicle to control a rubber blade on the windshield; similar devices had been made earlier, but Anderson's was the first effective model. Amazingly, car manufacturers initially didn't see the value in her invention; one Canadian firm declined her invention in 1905, saying "we do not consider it to be of such commercial value as would warrant our undertaking its sale." However, in 1922, Cadillac became the first car manufacturer to include a windshield wiper on all its vehicles, and after Anderson's patent expired, they quickly became standard equipment.

If you like coffee, you can thank German entrepreneur Melitta Bentz for making it easier to brew! Bentz was a housewife when she became frustrated with the difficulty of making coffee: percolators often over-brewed it, the espresso-style machines of her day left grounds in the drink, and linen bag filters were extremely difficult to clean. After experimenting with multiple materials, she struck on the idea of using blotting paper from her son's school exercise book, nested inside a brass pot perforated with a nail; she got a patent and set up a business to manufacture her filters. Within a year, she was selling hundreds of her filters, including 1,200 at the 1909 Leipzig Fair alone, and by 1928 her company employed dozens of people. She continued to improve her filter over the years, making it increasingly popular. Bentz was beloved by her employees for her generous bonuses and work schedules, and she also created "Melitta Aid", a social fund for her company's workers. And if the name sounds familiar, don't be surprised: the Melitta Group is still making coffee, coffee makers, and filters today.

Martin Cooper (born December 26, 1928) is an American engineer. He is a pioneer in the wireless communications industry, especially in radio spectrum management, with eleven patents in the field. Known for Inventor of the first handheld cellular mobile phone.
On April 3, 1973, he placed the first public call from a handheld portable cell phone at Motorola. Cooper reprised the first handheld cellular mobile phone (distinct from the car phone) in 1973 and led the team that re-developed it and brought it to market in 1983. He is considered the "father of the (handheld) cell phone" and is also cited as the first person in history to make a handheld cellular phone call in public, namely in 1973.

Cooper is co-founder of numerous communications companies with his wife and business partner Arlene Harris;[8] He is co-founder and current Chairman of Dyna LLC, in Del Mar, California. Cooper also sits on committees supporting the U.S. Federal Communications Commission[9] and the United States Department of Commerce.

In 2010, Cooper was elected a member of the National Academy of Engineering for leadership in the creation and deployment of the cellular portable hand-held telephone.
