DIY Theodolite.

A theodolite is a relatively simple instrument for measuring vertical and horizontal angles. It's commonly used for surveying, but you can also use one to get a rough estimate of the curvature of the Earth by measuring how far the horizon falls below eye level from different altitudes.

Modern theodolites are now often digital and expensive, but the classic theodolite still works quite well for this purpose. A classic theodolite, like the Würdemann model seen above, consists of an adjustable base that you set to level with adjustment screws and spirit levels. You then use a telescope with a crosshair to sight the distant object (the horizon in our case) and then read off the angle of the telescope for the circular scale.

You can then measure the dip of the ocean horizon from various altitudes. While...

Conspiracy oriented Intellihub is claiming that a large cargo plane spotted flying low over California accompanied by ten small jet planes was possibly transporting nuclear weapons to Korea.

This is a false, and only a few minutes research revealed that the planes were the French airforce demonstration team, Patrouille de France, who were in Sacramento for an air show, and later flew in the this formation over San Francisco. The cargo jet is a french Airbus A400M

What looks like two suns, one bigger than the other, were observed in Harrow, UK, recently. Video was show at:
https://weather.com/news/trending/video/which-sunset-was-real

Posted on April 11 2017, 03:15, so was likely from the previous day, April 10th.

An opposing sunset is usually a cloud lit by the sun. This one looks a bit unusual though.

Not new 27 photos pentagon metabunk.

Several news sites and 9/11 conspiracy groups are reporting that 27 "new" photos of 9/11 were just released

However they are not new, they were released in 2011. The confusion seems to just be due to a reorganization of the FBI's web site.

The photos can be found on the following web page:
https://vault.fbi.gov/9-11-attacks-...terials/9-11-attacks-and-investigation-images

And archives date it back to 2011.

20170327-131533-c1r7x.

I took the above photo today. It shows some Cumulus mediocris clouds. Medium sized cumulus. There are some people who think that these small fluffy clouds are the only type of "real" clouds that exists, and that high clouds such as cirrus or odd looking clouds like mammatus are evidence of some kind of global plot to modify the climate. Less extreme, but still overly suspicious, folk think that there are new clouds that exist in addition to the ten they were taught at school.

This suspicious was no doubt compounded when the World Meteorological Organization announced last week that the International Cloud Atlas was being modified to include...

20170325-090138-7044g.

Last year I created a physical model to illustrate some aspects of the WTC Tower collapses. The basic structure was columns connected by floors. The floors supply lateral stability to the columns, so when the floors are removed the columns are very unstable. This worked out reasonably well, and I got this nice demonstration from it:

I'm currently re-creating my physical model as a virtual model using Blender physics to allow for a larger variety of experiments, and also to illustrate the difference that scale makes.

The first version I tried quite...

This image has been circulating on social media and "tabloid" news sites, with claims that it shows a "human shaped cloud" or ghost hovering above a Zambian shopping centre:

The video of a Jet Airways flight being intercepted by German fighter jets is causing a bit of interest on social media, both due to the very visible contrails (enhanced by the video being filmed near sunset) and by the appearance of a "UFO":


Source: https://www.youtube.com/watch?v=iJALftSN0ek

Flight 9W118 from Mumbai to London on February 16th 2017, a Boeing 777, was intercepted after it failed to respond to air traffic control on the correct frequency over Germany.

The video was shot from a British Airways 777 flying behind it and 2,000 feet higher (flight BA2042).

The "UFO" appears to fly from left to right (and slightly "forwards", ie towards the same direction as the filming plane rather than perpendicular) from around 1:26 in the video:

Multiple fake news and clickbait sites are repeating variations of a story that FEMA expects the Oroville dam to collapse, killing thousands of people. This story is false. The source quoted is KCRA:
http://www.kcra.com/article/fema-su...ce-base-in-case-of-oroville-emergency/8944641
Perhaps the most obvious clue there is that only "two dozen" personnel have been deployed. Not a lot for the "worst disaster in American history".

But the facts...
