A few more 3D Geometrical figures:
æ£å…«é¢ä½“ – ã›ã„ã¯ã¡ã‚ã‚“ãŸã„ – regular octahedron
æ£å…é¢ä½“ – ã›ã„ã‚ãã‚ã‚“ãŸã„ – regular hexahedron
平行å…é¢ä½“ – ã¸ã„ã“ã†ã‚ãã‚ã‚“ãŸã„ – parallelepiped
å角柱 – ã¯ã‚“ã‹ãã¡ã‚…ㆠ– antiprism
トーラス – ã¨ãƒ¼ã‚‰ã™ – torus
レンズ – れん㚠– lens
And something beyond 3 dimensions:
超立方体 – ã¡ã‚‡ã†ã‚Šã£ã½ã†ãŸã„ – hypercube
and while we’re a it, dimensions:
一次元 – ã„ã¡ã˜ã’ã‚“ – one dimesion
二次元 – ã«ã˜ã’ã‚“ – two dimensions
三次元 – ã•ã‚“ã˜ã’ã‚“ – three dimensions
四次元 – よã˜ã’ã‚“ – four dimensions
Note the difference between the physical dimensions and the dimensions of numbers:
二元数 – ã«ã’ã‚“ã™ã† – 2 dimensional numbers
四元数 – ã—ã’ã‚“ã™ã† – quaternian
八元数 – ã¯ã¡ã’ã‚“ã™ã† – octonian

In a continuation of the geometry theme, let’s move from 2D geometry to 3D.
First, simple extensions of two dimensional objects:
円柱 – ãˆã‚“ã¡ã‚…ㆠ– cylinder (extension of a circle)
立方体 – りã£ã½ã†ãŸã„ – cube (extension of a square)
直方体 – ã¡ã‚‡ãã»ã†ãŸã„ – cuboid (extension of a rectangle)
The extensions of two dimensional polygons are prisms:
角柱 – ã‹ãã¡ã‚…ㆠ– prism
三角柱 – ã•ã‚“ã‹ãã¡ã‚…ㆠ– triangular prism
四角柱 – ã—ã‹ãã¡ã‚…ㆠ– square prism
五角柱 – ã”ã‹ãã¡ã‚…ㆠ– pentagonal prism/column
å…角柱 – ã‚ã£ã‹ãã¡ã‚…ㆠ– hexagonal prism/column
七角柱 – ã—ã¡ã‹ãã¡ã‚…ㆠ– heptagonal prism/column
八角柱 – ã¯ã£ã‹ãã¡ã‚…ㆠ– octagonal prism/column
A slight modification to an extension creates a cone or pyramidal shape:
å††éŒ – ãˆã‚“ã™ã„ – cone
ä¸‰è§’éŒ – ã•ã‚“ã‹ãã™ã„ – a three sided pyramid (tetrahedron)
å››è§’éŒ – ã—ã‹ãã™ã„ – a four sided pyramid (square pyramid)
äº”è§’éŒ – ã”ã‹ãã™ã„ – a five sided pyramid (pentagonal pyramid)
å…è§’éŒ – ã‚ã£ã‹ãã™ã„ – a six sided pyramid (hexagonal pyramid)
Now, more uniquely three dimensional objects:
çƒ – ãゅㆠ– sphere
çƒä½“ – ãã‚…ã†ãŸã„ – solid sphere
回転楕円体 – ã‹ã„ã¦ã‚“ã ãˆã‚“ãŸã„ – spheroid
æ‰å¹³æ¥•円体 – ã¸ã‚“ãºã„ã ãˆã‚“ãŸã„ – oblate spheroid
æ‰é•·æ¥•円体 – ã¸ã‚“ã¡ã‚‡ã†ã ãˆã‚“ãŸã„ – prolate spheroid
トールス – ã¨ãƒ¼ã‚‹ã™ – torus
Obviously, there are many more geometric figures, but this seems like enough for one post.

Although they may already be familiar, it is important to be sure you know the basic geometric shapes:
円形 – ãˆã‚“ã‘ã„ – a circle
三角形 – ã•ã‚“ã‹ãã‘ã„ – a triangle
æ£æ–¹å½¢ – ã›ã„ã»ã†ã‘ã„ – a square
四角形 – ã—ã‹ãã‘ã„ – a quadrilateral
長方形 – ã¡ã‚‡ã†ã»ã†ã‘ã„ – a rectangle
五角形 – ã”ã‹ãã‘ã„ – a pentagon
å…è§’å½¢ – ã‚ã£ã‹ãã‘ã„ – a hexagon
七角形 – ã—ã¡ã‹ãã‘ã„ – a septagon/heptagon
å…«è§’å½¢ – ã¯ã£ã‹ãã‘ã„ – an octagon
In these words, 「ã‹ãã‘ã„〠can alternatively be pronounced 「ã‹ã£ã‘ã„ã€, which is a little easier to pronounce.
Equilateral shapes are prefixed with ã€Œæ£ – ã›ã„ã€.
æ£ä¸‰è§’å½¢ – ã›ã„ã•ã‚“ã‹ãã‘ã„ – equilateral triangle
æ£å…è§’å½¢ – ã›ã„ã‚ã£ã‹ãã‘ã„ – equilateral hexagon
There are several specific triangles and quadrilateral with specific terminology:
二ç‰è¾ºä¸‰è§’å½¢ – ã«ã¨ã†ã¸ã‚“ã•ã‚“ã‹ãã‘ã„ – isoceles triangle
直角三角形 – ã¡ã‚‡ã£ã‹ãã•ã‚“ã‹ãã‘ã„ – right triangle (「直角 – ã¡ã‚‡ã£ã‹ãã€is right angle)
直角二ç‰è¾ºä¸‰è§’ – ã¡ã‚‡ã£ã‹ãã«ã¨ã†ã¸ã‚“ã•ã‚“ã‹ãã‘ã„ – isoceles right triangle
黄金四角形 – ãŠã†ã”ã‚“ã—ã‹ãã‘ã„ – golden rectangle
å°å½¢ – ã ã„ã‘ã„ – trapezoid
平行四辺形 – ã¸ã„ã“ã†ã—ã¸ã‚“ã‘ã„ – a parallelogram
è±å½¢ – ã²ã—ãŒãŸ – a rhombus
凧型 – ãŸã“ãŒãŸ – kite shape
Of course, there are a variety of other two dimensional figures, some of which I will list here:
楕円 – ã ãˆã‚“ – ellipse
五芒星 – ã”ã¼ã†ã›ã„ – pentagram
å…芒星 – ã‚ãã¼ã†ã›ã„ – six pointed star/star of david
ãƒãƒ¼ãƒˆå½¢ – ã¯ãƒ¼ã¨ãŒãŸ – heart shape
Not shapes, but two dimensional lines:
åŒæ›²ç·š – ãã†ãょãã›ã‚“ – hyperbola
放物線 – ã»ã†ã¶ã¤ã›ã‚“ – parabola
There are many other shapes, but I think this covers the basic geometric shapes of particular mathematical significance fairly well.

å¤ä»£ã®å·¨å¤§ãƒšãƒ³ã‚®ãƒ³ã€ç™½é»’ã§ã¯ãªã‹ã£ãŸ
——————————————-
å¤ä»£ – ã“ã ã„ – ancient times
巨大 – ãょã ã„ – giant
ペンギン – ãºã‚“ãŽã‚“ – penguin
白黒 – ã—ã‚ãã‚ – black and white
I like the phrase “å¤ä»£ã®å·¨å¤§â€. The similarity of the sounds is a nice combination of alliteration and rhyme.
The basic properties of the bird are disclosed in the second sentence:
人間ã®èƒŒä¸ˆã¨å¤‰ã‚らã¬ä½“é•·ã§ã€èµ¤èŒ¶ã¨ç°è‰²ã®ç¾½ã‚’見ã«ã¾ã¨ã£ã¦ã„ãŸã¨ã„ã†ã€‚
人間 – ã«ã‚“ã’ã‚“ – human being
背丈 – ã›ãŸã‘ – height
変ã‚ら㬠– ã‹ã‚ら㬠– constant/same
体長 - ãŸã„ã¡ã‚‡ã† – length
So the first part of the sentence says the bird was equal in length to human height.
赤茶 – ã‚ã‹ã¡ã‚ƒ – reddish-brown
ç°è‰² – ã¯ã„ã„ã‚ – gray
ç¾½ – ã¯ã – feathers
身ã«ã¾ã¨ã† – ã¿ã«ã¾ã¨ã† – be dressed in, covered in
So the bird was the height of a human and covered in reddish brown and gray feathers.
The 「ã¨ã„ã†ã€at the end indicates that this is what the researchers are saying, making it somewhat clear that this is not certain but is speculation, although based on research and evidence.

温暖化 – ãŠã‚“ã ã‚“ã‹ – warming

Global warming is presumably caused by the burning of fossil fuels.
化石燃料 – ã‹ã›ããんりょㆠ– fossil fuels
Notice the word 燃料 is the same as in the Whirlwind of Fire article.

ç«ç½æ—‹é¢¨ã®ææ€–: 燃料ã¨ãªã‚‹ã‚¬ã‚¹
——————————————-
ç«ç½ – ã‹ã•ã„ – a fire
旋風 – ã›ã‚“ã·ã† – whirlwind
ææ€– – ãょã†ãµ – fear, dread, horror
燃料 – ãんりょㆠ– fuel
ガス – ãŒã™ – gas
ã¨ãªã‚‹ – to become
ç«ç½ indicates a house fire, wildfire, or similar, which you might guess due the use of the same kanji as in:
å¤©ç½ – ã¦ã‚“ã•ã„ – natural disaster
The photo in the post is of a fire whirlwind above a burning peat bog in England. I’m not totally sure about the scale of the photo, but it doesn’t look that big to me, so it seems like ææ€– might be somewhat overdramatic.
