Thurs April 19 2012 Roses are red, but can be blue...
« on: April 19, 2012, 09:57:14 am »
                                       


                                        Roses are red
                                        but can be blue
                                        if at great speed
                                        they come towards you.

                                        At one hundred million
                                        meters per second
                                        red becomes blue
                                        in visual spectrum.

                                        Rose breeders seek
                                        a true blue rose.
                                        Hybrids still are
                                        purple and mauve.

                                        On rose seller’s shelves
                                        soon you'll find them:
                                        Rosa “Blueshift”,
                                        a fast-moving item.

That's brilliant, Budgieye! ;D ;D ;D ;D

Update: I tweeted this and it is very popular, lots of people showing it to all their followers, including NatureNews&Comment! The pithiest comment so far is "If roses come to you at such a speed they were probably thrown back at you for a reason."

Several years ago Japanese spirits maker Sun-Tory contracted with an Australian firm to make a true blue rose.  The Ozzies transgenically took a gene for delphinidin from a Petunia and shotgunned it into roses.  Results were sometimes strange, e.g. a rose with blue thorns, but sometimes they did get the gene inserted into the proper place to be turned on when flower pigment was being produced.  But there was a second problem.  Anthocyanins like delphinidin are pH sensitive, so another of them, cyanidin, makes red roses because roses have low pH, and blue Bachelor Buttons and Himalayan Poppies, because their pH is higher.  So the Ozzies had to also force in a change to the pH genes.  But this year they are introducing "Applause" to the North American market.  It was available in the Tokyo market in 2009.

p.s. Some Delphiniums are quite purplish too.  Delphinidin can be converted into malvidin, and petunidin which are more purplish.

It's highly unlikely you could accelerate a rose up to a third the velocity of light.
 Alternatively-

We read an OOTD, and many questions arose . . . ::)

Stole the words right out of my mouth.  ;)

Great OOTD, Budgieye.  8)

It sure is. I think this thread is now over 700 views, which is quite astonishing for the first few hours of an OOTD; probably hasn't happened since the earliest days of this forum ... If this brings new people to the forum, and new zooites who will begin classifying Hubble Zoo galaxy images, why, let's have more of them!   ;D

So, if you see a rose, which you know to be red, coming at you so fast that it appears blue, you'd better get out of the way ... being hit by a rose traveling that fast would not be pleasant.  ;D

It would be carrying huge energy. As it reached the top of the atmosphere it would be carrying very close to 1*1014Joule of kinetic energy travelling at 1/3 light speed. I weighed a rose with 3 inches of stalk ( 20 gram) maximum diameter 10cm; you don't want to get hit by the thorns :).

By comparison that kinetic energy is equivalent to 55 1 tonne cars travelling at 30mph or 1 Abrams tank if you prefer. The rose is travelling far far faster than any meteorite or astrobleme impact. Don't expect the petals to fall off :o. The atmosphere does extend above 100 miles. You might see a flash of visible light but not enough time to process it within 0.25 second as perhaps the visible component of a gamma ray burst, as your brain atomises to produce a huge number of elementary particles. The air can't get out of the way of that 10 cm diameter rose and it compresses and heat up to millions of Kelvin degrees. The hot plasma and still 20 gram of rose atomises you , not enough time for the piments to change colour,  as it bores into bedrock beneath your feet. How big a crater does it create, 1m, 10m, 100m, 1 km etc? Who knows what other flowers or flying pigs or cats out there might pose future hazards? Look on the bright side-it's an efficient form of cremation although the landscape might become pockmarked. What about anti roses!? A bunch of a dozen of them would represent a 1 megatonne bomb.

Infact, Budgie's roses are indeed a bunch, a dozen or possibly a baker's dozen, but not a cheap skate 10. Would anti roses look red or anti red? This is a deeper question infact that needs years of study before a brief answer suffices -yes red but maybe not quite so.

 On an adjacent table and talking about flying cats, I had heard a french couple ask for a gateau au chocolat as a dessert or pudding. The waiter brought them this excellent cake. Twenty minutes later when we too required a dessert, a different and younger waiter approached the table and then rattled offabout six desserts in Catalan and then Spanish to us. I knew three of them but not all and the all didn't include this delectable cake. I said to my wife; Julia there's no cake, perhaps the last slices had gone. "Excuse me" I added in execrable Spanish, several times and many variants variontos, gateau please con chocolate. He looked stunned. Gateau, tarta con anything , frutas. He looked increasingly shocked as , thick as I was after all the wine, gateau in the name of God gateaux, gateau Francais(e); those Frenchies got it. Fortunately, the other older waiter came over as the younger one failed to accommodate these north European paganos, bloody camposinos, terrinazos. El gato (cat). Of course I knew what a cat was! "Oh- he thinks I was asking for baked cat in chocolate" I said to Julia. Infact, they all had such a horrendous laugh out back in the cocinera that they brought us a double helping of this excellent flying cake.
