【推荐1】Welcome to the World Wide School—the best place on the Internet to learn just about anything. Just read, click and learn. We wish you the best.

This site is dedicated to (致力于) the collection, preservation and presentation of educational materials. To attend the World Wide School, all you need to do is devote your time.

For whatever reason, many people may find it difficult to further their education by traditional means;attending high school or college can seem like an impossible dream. That is why we are offering education through the Web.

The Hart Library

We are still stocking the Hart Library, a complete library containing everything from novels, poetry to reference materials.

Please note that many of the books and other works provided on this site were written many years ago, before the invention of the radio, atomic bombs and cars. Some are even older, written when the world was run by kings and queens, and most people did not know how to read them. The works reflect the times in which they were written, and many contain views about race, religion, science and other things that we find annoying or just wrong today.

We believe that part of the value of these works is the window they provide on the past. By providing these books we do not mean to present any point of view, except that education and reading are good.

【推荐2】The creators of Mission to Mars AR meant it to be educational, with plenty of up-to-the-minute facts and figures about Mars exploration. But don’t let that put you off. It’s also a lot of fun. And it shows how far phone-based AR has progressed in the four and a half years since Pokémon Go, a 2016 AR mobile game, sent millions of people out into the streets searching for imaginary creatures.

The free app, which comes out in time for next week’s landing of the Perseverance rover (探测器) on Mars, is nearly identical in design to the Smithsonian Channel’s Apollo’s Moon Shot released for the 50th anniversary of the moon landing in 2019. In that one, you could use your phone to send a virtual Saturn V rocket into space, and learn about the Apollo astronauts and their machines through more than a dozen interactive experiences. Take some photos on the moon, suited up in the Apollo 11 spacesuit, and share with friends on social media.

Simple AR has taken off in shopping apps and social media in recent years. But Mission to Mars AR shows that the technology is capable of much more than just adding rabbit ears or cool sunglasses to your selfies (自拍). The app offers seven experiences, starting with an overview of Martian geography. Turn the globe in front of you to inspect the planet’s frozen polar caps and vast valleys.

The experiences in Mission to Mars AR add a bit more challenge, but are easy to master after a couple of tries. Guide Perseverance through its “seven minutes of terror” — NASA’s now semi-official term for a Mars landing. The “Mission to Mars” module offers the most interaction. You guide the rover from rock to rock, using a laser to analyze their contents while being careful not to crash or get stuck in the sand. You can even fly a small helicopter on Perseverance, which is sure to be one of the real mission’s highlights.

Just as NASA rovers have advanced from tiny Sojourner in the 1990s to Perseverance, we’ve come a long way from just downloading Mars photos for our desktop wallpaper.

【推荐1】Depending on your thinking, Violet Jessop was either the luckiest or unluckiest women to ever live. Either way, she certainly has one of the most interesting stories you'll ever read.

Jessop was a waitress on ocean liners who began her career aboard the Orinoco in 1908 at age 21. She started with the White Star Line company when she went aboard the HMS Olympic, one of three Olympic class ships created by the company, in 1910.

A year later while Jessop was still working aboard the ship, it hit a British warship the HMS Hawke. Though both ships were damaged in the accident, it did not completely destroy either ship and there were no injuries or deaths.

While the Olympic was being repaired, Violet was employed board another White Star Line ship, and the sister ship to the Olympic, the RMS Titanic. Jessop was on board when the Titanic stuck an iceberg and sank, but was able to find a lifeboat and survived.

Although she had been a part of these two sea accidents, Jessop was undeterred, and during World War I, she served as a Red Cross stewardess aboard the HMHS Britannic.

It had been changed into a hospital ship and was transporting injured soldiers to the United Kingdom when they hit a German mine in the Aegean Sea and sank.

Whole escaping the sinking ship on a lifeboat, Jessop and many other passengers were almost sucked into the ship's propeller blades, but narrowly escaped, strengthening her fame as “Miss Unsinkable”. She would later tell bet sad story in Titanic Survivor: The Newly Discovered Memoirs of Violet Jessop who Survived Both the Titanic and Britannic Disasters.
