Earth puzzle

Explore the Earth and Moon through our mind-bending, never-ending jigsaw puzzles. Start anywhere and see where your journey takes you. This puzzle is based on an icosahedral map projection and has the topology of a sphere. This means it has no edges, no North and South, and no fixed shape. Try to get the landmasses together or see how the oceans are connected.

Make your own maps of the earth! A classic map imposes distortions and orientations that reflect our preconceived notions of the world. The Mercator projection, which is the map we are most familiar with, unrolls the globe into a rectangle with even spacing of latitude and longitude, inflating Greenland into a massive tundra and smearing Antarctica into an unrecognizable white smudge at the bottom.

It makes it seem like the Arctic is impassably vast, when actually flying over it is the fastest way to get to Europe from the US. More subtly, it reinforces the idea of a world split into West and East. Even a true globe typically has a fixed North-South axis, forcing us into a certain viewpoint. The Earth puzzle is based on type of map called a polyhedral projection, where the sphere is projected onto a shape with planar faces and then unfolded flat.

In this case, the globe is projected onto a icosahedron, a 20 sided shape of equilateral triangles. This reduces the distortion seen in most maps. This type of map was most famously explored by Buckminster Fuller with his Dymaxion Map.

However, unlike the Dymaxion Map, our map is equal-area, meaning the relative size of landmasses is preserved exactly. We created software to turn a Mercator projection into an icosahedral one.

We use a technique called spherical barycentric coordinates to project the sphere onto the icosahedron. These are area coordinates where every point on a triangle is identified as the weighted sum of its 3 vertices. If you take a point in a triangle and use that to subdivide the triangle into three smaller triangles, then the weight associated with each vertex is proportional to the area of the opposite triangle.

Barycentric coordinates are commonly used in computer graphics to interpolate quantities on triangular meshes. You can extend this idea to spheres using spherical triangular patches and their areas. By doing so, the same area on the sphere corresponds to a proportional area on the icosahedron.

The whole thing works in a GLSL shader. First we draw a triangle and its barycentric coordinates. We use those coordinates to compute a point on the sphere using spherical barycentric coordinates. From that point, we get the latitude and longitude, which allows us to look up the texture of a Mercator map.

We used the tool to design the projection such that the vertices of the icosahedron do not lay on land. The vertices are the only fixed point of the puzzle, and a seam must pass through them in order to make the puzzle flat.

By putting the vertices in the ocean, it means all continents can be assembled into continuous shapes. While Fuller always envisioned his Dymaxion Map as reconfigurable, we take this one step further by making a piece puzzle with no edges.

There is no fixed orientation or configuration of the puzzle. Assemble it such that all the continents form an almost continuous land mass or put all the oceans together.

Put Antarctica in the center. The Infinity Puzzles are puzzles that truly have no border: pieces wrap around connecting from one part to another. There is no fixed final shape. The first Infinity Puzzles tile, connecting the left to the right and the top to the bottom. This demonstrates how the infinity puzzles are not simply tiling puzzles but represent a broader range of possible borderless puzzles.

The Earth Puzzle can be assembled into countless shapes because it has the topology of a sphere and pieces wrap around with a rotation.Visual Skills - No Rotation of Images 2 by 2: Multiple Choice - Easy printable 2 by 2: Full image given 2 by 2: Picture is one-fourth complete 2 by 2: Full image given one extra piece not used 2 by 2: Picture is one-fourth complete one extra piece not used 2 by 2: Full image given two extra pieces not used 2 by 2: Picture is one-fourth complete two extra pieces not used 2 by 3: Full image given 2 by 3: Picture is one-sixth complete 2 by 3: Full image given two extra pieces not used 2 by 3: Picture is one-sixth complete two extra pieces not used Mixed Book - one page of each worksheet.

We believe in ethical reviews and responsible gambling at all times.To represent the difference between the two teams that are playing in the matchup, the ratio or the difference between the same attributes are taken between the two teams. Therefore, when attributes are a positive indicator of performance, a value greater than 1 indicates that the home team performs better for that particular attribute.

Examples of this are win streak, compared to statistics such as points per game that would be compared by taking the ratio. Web Scraping The data is scraped from several websites according to each sport using Python and the Selenium and BeautifulSoup (only for MLB data) packages for Python. Data sources for each sports are described in the "Link" section.

Game stat data, team stat data, and datetime data are merge later into a feature file (. In the same scripts, After having obtained the raw data set, data is cleaned throughout the script. The script checked the completeness and validity of all the data files, and eliminated any CSV parsing errors or erroneous data values. Here is the main idea: Having validated all our available data, the script then proceeded to load the data from the csv files into an SQL database using the SQLite single-file database engine and a few Python scripts.

The flexibility of SQL queries allowed one to easily perform complex joins and merges between multiple tables via the the script. Thus, the script converts the clean scraped data to data structures that the libraries in scikit-learn can easily use. The ultimate result of the routines included in this file is a numpy array containing all the features and game results for the historical game data.

The features have not been normalized but the next script provide one the ability to easily normalize or standardize the data.

We took more than 2500 pics, we drove more than 3300 Km. We met many friends on the way - most of them "Nordic people". The service provided and information received before the tour was excellent. The standard of accommodation was excellent, for me the best experience was sleeping in the national park, however every single hotel was wonderful.

We had the best guide-driver we could dream of. For us he was more than a guide. I have a deep respect and admiration for Asgeir who helped us to discover, understand and fall in love with this beautiful country. He adapted himself so kindly to our needs and tantrums. My daughter keeps talking about him.

I do not exaggerate when I say he is her hero. Now everyone knows him in France and in England.
