What happened to the guy at the beginning of this video?


Also, is the location really in Tennessee, and if so, where specifically? 142.117.133.114 (talk) 09:38, 16 April 2024 (UTC)


 * Here he was mud diving in the Netherlands and here in the UK. And here in New Zealand. Sadly, after he disappeared while mud diving in Tennessee, he was never heard of again. This should be a sobering lesson for all of us. --Lambiam 19:20, 18 April 2024 (UTC)

“lakipadada” or “lakipadaja”
Early Indonesians, particularly the Bugi people and Makassar people from Sulawesi, created navigational charts known as “lakipadada” or “lakipadaja”. These charts were made using various materials, including shells, wood, and bamboo, and they depicted ocean currents, wind patterns, and celestial navigation points. The intricate designs and detailed knowledge encoded in these charts facilitated navigation across the vast Indonesian archipelago. Do we have anything about these charts? ◅ Sebastian Helm 🗨 15:42, 16 April 2024 (UTC)

NCEI
Does the NCEI have any data in metric units? It seems that non-US climate data is reported in Fahrenheit. But the same data is also in KNMI Climate Explorer, and there in metric units. So, is there any data in metric units there? --40bus (talk) 16:54, 16 April 2024 (UTC)
 * If necessary, it is trivial to convert a data column from one unit to another. Because temperatures are often rounded to the nearest integer, being in Fahrenheit provides a little more precision than Celcius. But, that is not an argument to always use Fahrenheight. I am simply pointing out that being in Fahrenheight does not mean it is unusable data. As an example, you can use =(F1-32)/1.8 in Excel to get the value in F1 as Celcius. — Preceding unsigned comment added by 75.136.148.8 (talk) 18:25, 17 April 2024 (UTC)
 * Almost all non-US climate data is recorded by the respective nations it belongs to in Celsius. If an American agency is reporting that data in Fahrenheit, that agency must be doing a conversion itself. As the person who wrote the program to convert Australia's climate data to Celsius back in the 1970s, I find that rather amusing. HiLo48 (talk) 00:19, 18 April 2024 (UTC)
