Rebuilding Han and Ming

If we don't build an army, we will have nothing to gain in many industries.

This is a good book, but it is not a good novel 🤦

This book sums up "National Geographic Magazine" in one sentence!

The clock is very accurate when it is on land, but when it is affected by wind and waves at sea, the accuracy cannot meet the requirements. John Harrison's ultimate achievement, the H4 marine clock, used a hairspring pendulum structure, coupled with various error reduction schemes when he studied H1~H3, and successfully produced a qualified marine clock. Due to the use of a hairspring pendulum structure, the H4 marine clock is very compact. H1 is one meter square and weighs 34 kilograms. H2 is slightly smaller but heavier. H3 is 60 centimeters high, 30 centimeters wide and weighs 35 kilograms. Ball bearings were invented and used in H3. The H4 is 13 centimeters in diameter and weighs 1.45 Kilograms, like an enlarged pocket watch, and finally met the requirements of the Longitude Committee.

This book should be renamed "History of Science and Technology Development in the Ming Dynasty", the background data is too detailed. It's so detailed that I don't have space to write about the plot, and the plot is all covered in one stroke 🤦

The writing is very good but the information is too detailed. Who can memorize so much information? After all, I am here to read the novel and not to learn the information. The problem is that even if I study, I will not be able to go back to the past and make a fortune.

The author's knowledge is very broad, covering history, geography, machinery, metallurgy, chemical industry, and textiles. One less star means higher requirements for readers.

The protagonist's brain is smarter than a computer😥

The writing is too detailed, and it must have been written for thousands of chapters! Come on, I haven't read such a detailed book in a long time 🤦

Awesome, it's a super geographical encyclopedia.
