The Panama Canal is not a sea-level canal. The boats are lifted up to Gatun Lake, then lowered down the other side. Also, there's a 20 cm difference between the mean sea level of the Atlantic and Pacific sides, the tides on the Atlantic vary by about 1 meter while on the Pacific side by about 6 meters, and the timing of the tides is different. De Lesseps's plan (the original French effort before the US one) was a sea-level canal. It would still have required a sea lock on the Pacific side to handle the tides.
As to how they surveyed it, they set up a geodetic network based on triangulation. There were several surveying teams (US and French) which went to the area to survey it, establishing triangles across the isthmus. Perhaps the greatest example of this kind of work in the 1800s is the Great Trigonometrical Survey of India, of which there are several books if the topic interests you.
Ummm, the comments section is a place to engage in discourse -hence the reason it's a public forum vs. an email. If you can't grasp that basic concept then you obviously know nothing about the internet. This assertion is further backed up by the fact that you think something should be deleted just because you find something wrong with it. Guess what? If the internet worked like that, there would be no internet.
If you can't accept these basic concepts then please get off the internet (and general society) altogether and go live in your closed-off world where no one ever disagrees with you.
It's a tradition that dates back to 1813. After the Battle of Lake Erie, Canadians developed long, extendable, mechanical arms to reach across the water (which they could no longer control through conventional naval forces) and raid American territory for potatoes (for making poutine).
If you want your remark to be directed to "the management" then I suggest you use the email address to contact them directly, rather than put it in a public forum where others will respond to it. Just an idea.
I am overwhelmed. I would not have been so gracious for the first gift as this boy, who apparently must glue his shoes to repair them as a normal part of his life. It makes you want to start a Kickstarter for him to raise a scholarship or something.
Automated, cow regulated, dairy farms exist now. The cows choose when to eat, be milked, etc. Some are quite luxurious with cow triggered brushes and misters. I was reading an account of one in the midwest where they frequently left the gate open for truck access and the cows would wander out and eat the rancher's lawn, only to come back in of their own accord.
I believe cows are already sentient, and intelligent enough to make their own choices to some degree. If it runs away and we have to capture it, it is a prisoner and slave.
