TECH-MUSINGS

Thoughts On Algorithms, Geometry etc. Friday, January 12, 2018. Note: This post reports some investigation done with help from K Sheshadri. Given an ellipse E, what is the least area (least perimeter) convex region for which E is the least area(least perimeter)ellipse containing the convex region? Note: The questions above can be generalized to higher dimensions. Among all 2D convex shapes without. 3 fold rotation symmetry, the ellipse is perhaps the only shape such that every point on its boundary is a ...

TECH-MUSINGS: On Reconstructing Convex Polyhedra (Contd.)

http://nandacumar.blogspot.com/2013/02/on-reconstructing-convex-polyhedra-contd.html

Thoughts On Algorithms, Geometry etc. Saturday, February 23, 2013. On Reconstructing Convex Polyhedra (Contd.). This post continues the last post here. Ramana Rao found a set of polygonal faces which can form different convex polyhedra with different volumes. See the following page: http:/ www.korthalsaltes.com/selecion.php? Further question: Are there face sets where not all faces are identical and which generate distinct polyhedra with different volumes? Posted by R.Nandakumar @ 9:47 AM. Congruent Part...

TECH-MUSINGS: Filling the Plane with non-Congruent pieces

http://nandacumar.blogspot.com/2014/12/filling-plane-with-non-congruent-pieces.html

Thoughts On Algorithms, Geometry etc. Wednesday, December 10, 2014. Filling the Plane with non-Congruent pieces. Question: Consider the set of all triangles with the same specified area and perimeter - there is an infinity of them (aleph 1 it seems) except in degenerate cases. Can a selection of unique triangles from among this set fill the plane without gaps or overlaps? Can this be done for all valid and non-degenerate area-perimeter combinations? That raises the issue:. Update (Dec 31, 2014): Another ...

TECH-MUSINGS: Permutations Using Stacks

http://nandacumar.blogspot.com/2014/11/permutations-using-stacks.html

Thoughts On Algorithms, Geometry etc. Thursday, November 06, 2014. NOTE (November 11th 2014): The problem presented here was first studied by Knuth back in 1968. Several other leading experts went on to add formidable details (as basic references, there are Wiki articles on 'stack sortable permutations' and so forth). I was unaware of all that when I started on this problem and did what now can only be called very basic experimentation. But I let the article be as it was written:. Note: one needs to call...

Thoughts On Algorithms, Geometry etc. Thursday, October 19, 2006. Fair Partitions - III. This is the third part of the present trip of partitioning *convex* polygons into equal area pieces with additional constraints. We (Ramana Rao and self) make an attempt to solve a specific case of the larger problem - to split a triangle into 3 convex pieces with equal area and perimeter. Cutting a triangle into 3 pieces of equal area and perimeter:. A simple specific example or the argument:. 3 Note that at the ini...

TECH-MUSINGS: Partition into Isosceles Triangles

http://nandacumar.blogspot.com/2015/08/partition-into-isosceles-triangles.html

Thoughts On Algorithms, Geometry etc. Saturday, August 08, 2015. Partition into Isosceles Triangles. Question: What is the best way to partition a given polygon into isosceles triangles? What is known to us: One has an upper bound of 4*(n-2) isosceles triangles for any n-gon. Indeed, the n-gon can be cut into n-2 triangles and each triangle cut into 4 isosceles triangles. What follows is based on Martin Gardner's 'New Mathematical Diversions':. Question: So, does one have a tight upper bound of 8(n-2) fo...

The Blog) With No Name', perhaps best described as a stream of notes and thoughts - 'remembered, recovered and (sometimes) invented'. Monday, January 30, 2006. I paid one chap fifteen thousand bucks and did a certificate in 'hardware'. I had great difficulty in understanding the books but worked very hard; but now it seems 'software' is better for a job and I feel lost. These are hard times. But what to do, I come here every morning and do some exercise on the lawns and share some information...The story...

The Blog) With No Name', perhaps best described as a stream of notes and thoughts - 'remembered, recovered and (sometimes) invented'. Friday, July 29, 2005. Just like any other temple-site, there is a legend associated with this place; indeed this story is but a small fragment from a vast cycle of legends, myths and folklore called 'Parayipettu Panthirukulam' (well, there we go again! Whenever a baby was born to them, the husband would ask: "does the child have a mouth? The father 'seated' (buried? Beyon...

Henry Ford believes that even a machine needs rest. When asked why he favored short hours for workers, Henry Ford said that no good engineer will run even a machine at the limit of its power and speed for very long.

The Blog) With No Name', perhaps best described as a stream of notes and thoughts - 'remembered, recovered and (sometimes) invented'. Tuesday, September 27, 2005. This is on a doubt I have had for most of my life so far. More basically, did folks here in India know that the rainbow came from a play of Sunlight (unlikely)? Is it the case that in some culture, some folk-tradition, the rainbow has a different number of colors? Well, that, if true, thickens the plot quite a bit! Note 2: Probably, most Indian...

The Blog) With No Name', perhaps best described as a stream of notes and thoughts - 'remembered, recovered and (sometimes) invented'. Saturday, August 27, 2005. Note: The 'u' in the word is that of 'cut'; the 'a' is the one of 'shape'; and the 'e' at the end of this word ought to be pronounced as the 'e' in German word 'danke' or 'u' of 'Tamil Nadu' -well, these two sounds sound pretty close to me! Moreover, the 'd' and the 'l' are retroflexed). I muse: "well, that is a new word! Even in the 1970's.".

This is in continuation of the previous post here, reporting on a suspected sighting of the 'Kurinji' in bloom. At Kate's Point, Mahabaleshwar. Here is a slightly edited copy-paste of a mail from Shrikant Ingalhalikar, author of 'Flowers of Sahyadri', clarifying some of the issues therein:. Posted by R.Nandakumar @ 1:27 PM.

Light (and its interplay with matter) is the flavor of these days and here is a bit more. Is a page from the cluster of expository material maintained by John Baez. That white clouds appear perfectly white with no tinge of blue probably refutes the 'blue film' idea given above. But I have no better idea. Refraction of li...

The Blog) With No Name', perhaps best described as a stream of notes and thoughts - 'remembered, recovered and (sometimes) invented'. Friday, November 25, 2005. This is on a problem I worried quite a lot about a long time back:. I guessed at a quadrilateral (with all angles measuring irrational fractions of PI but summing to 2*PI) and tried to prove that it cannot be cut into any finite number of mutually identical tiles. The effort was but a partial success; however it resulted in this 'challenge'.

Nate, Allison and Jett. Saturday, October 27, 2012. Jett as a Pup-Pup/Gardner Village. Once he discovered he had a tail, he wouldn't let go. Gardner village is always decorated so cute during Halloween- we always love the witches. They also have a petting zoo that we have been to a couple times this year. Jett always runs around like he owns the place. He's never hesitant to go up to all of the animals and pet/sit on them. Today he was particularly obsessed with the bunnies. We love that little pup-pup!
