Works of prolific Russian-American writer Isaac Asimov include popular explanations of scientific principles, The Foundation Trilogy (1951-1953), and other volumes of fiction.

Isaac Asimov, a professor of biochemistry, wrote as a highly successful author, best known for his books.

Asimov, professor, generally considered of all time, edited more than five hundred books and ninety thousand letters and postcards. He published in nine of the ten major categories of the Dewey decimal classification but lacked only an entry in the category of philosophy (100).

People widely considered Asimov, a master of the genre alongside Robert Anson Heinlein and Arthur Charles Clarke as the "big three" during his lifetime. He later tied Galactic Empire and the Robot into the same universe as his most famous series to create a unified "future history" for his stories much like those that Heinlein pioneered and Cordwainer Smith and Poul Anderson previously produced. He penned "Nightfall," voted in 1964 as the best short story of all time; many persons still honor this title. He also produced well mysteries, fantasy, and a great quantity of nonfiction. Asimov used Paul French, the pen name, for the Lucky Starr, series of juvenile novels.

Most books of Asimov in a historical way go as far back to a time with possible question or concept at its simplest stage. He often provides and mentions well nationalities, birth, and death dates for persons and etymologies and pronunciation guides for technical terms. Guide to Science, the tripartite set Understanding Physics, and Chronology of Science and Discovery exemplify these books.

Asimov, a long-time member, reluctantly served as vice president of Mensa international and described some members of that organization as "brain-proud and aggressive about their IQs." He took more pleasure as president of the humanist association. The asteroid 5020 Asimov, the magazine Asimov's Science Fiction, an elementary school in Brooklyn in New York, and two different awards honor his name.

۱:زهره نزدیکترین سیاره به زمین است و بخاطر روشنایی دلپذیر و زیبایش، به ونوس معروف شده است.

۲:مدار سیاره زهره نزدیکترین مدار به دایره کامل است.
برخلاف سیارات دیگر که مداری نامتقارن دارند.

۳:سیاره زهره، پنج درصد کوچکتر از سیاره زمین است.
در سال ۱۹۶۲ آمریکا با فرستادن یک کاوشگر به سطح سیاره زهره دمای آن را برابر با ۴۷۷ درجه سانتیگراد تخمین زد. تا آن حد گرم که سرب را ذوب می‌کند.

۴:فشار جو زهره هشتاد و هشت برابر جو زمین است. انگار که کف یک اقیانوس ایستاده باشید.

۵:یک روز زهره برابر با ۲۴۳ روز زمین است.
