It IS Cyperus Esculentus, the Nut Sedge

so the other day i found a slightly different sedge, and looking carefully at the flowerspikes i decided it was a different species, and today i dug it up and found tubers:

here is Cyperus strigosus, which i see all over the place in moderately damp situatio s.  you can see it in the foreground, very full and spikey.  Behind it is a taller looser yellower sedge.

here is a closer comparison, C. strigosus on the right

even closer, notice strigosus on the right has long thin green keeled flower scales while the plant on the left has more smaller stubby browner scales

so, today i went back and dug up one of the flimsier sedges and found tubers. that's a tuber growing off of one of the roots beneath the sedge. It's Cyperus esculentus, nut sedge.  the tubers are supposed to be edible.  if i find a bigger mature patch maybe i will try.  probly gotta boil or roast them?

I will try posting my pics and drawings of 18 sedge species later.

reviewing sedges and rushes

worked on 13 species/speimens this week

here's a a little seed from... Eleocharis.. engelmanni?

i'll go back out to the field to get better shots
what else in my phone?
Scirpus atrovirens

these six lived in a small wet patch.  Ok, so know i know that the big red bunches are actually insect galls on the Juncus acuminatus.  which i also found samples of by my house

Critters On The Porch!

first we have an ant with a heart shaped butt: genus Cramatogaster
shiny little ant.  you can see the porch railing reflecting on her.

next a dusky Lasius ant.  this ant was VERY fast.  very hard to get a shot.
these ants are about a quater of an inch long..  Lasius you will find making a bunch of tiny volcano entrances to their nest along sidewalks and in other open places

next we have zebra jumping spider.  I should have tried to gt infront of it and get a good mug shot.
ok thats enough for today.

fire flies, central park, nyc

come summer in New York City,
the fireflies would apear in central park
and then at dusk the bats would come flitting out.
bats and fireflies,
bats chasing fireflies,
bats devouring the firefly crop.
lighness and dark.

one night there was a dance performance at summerstage and these woman were behind these tubs dancing as if they were washing their hair and then all of a sudden they all dip their hair in the tubs and swirl their heads up and...

there was REAL WATER in the tubs and these arcs of water went up into the air lit by the lighting and down...

all over the stage


'cause the women were still dancing

and even on the slippery wet stage they kept dancing

and all through it fireflies flitting between them

and the bats

Math Puzzle Time: surround three

So that's the puzzle.  I think this was mixed up in my mind with something called frustrated systems and maybe generally, can crystal growth come up with something arbitrarily complexity.  At first I found plenty of boring solutions:

Even radially symmetric ones

Even spirals!

but were there TRULY CREATIVE solutions possible?  Two weeks later, it came to me:

Now... can I write an algorithm to do that?  Better yet, a set of local cellular automata rules that force it?  Better yet... is there a mineral out there that does this?

Can anyone find other kinds of solutions?

Convincing Geologists That The Continents Move (part of history of science in 100 tweets)


science works by exploring every possible thing with wildly different tools and approaches and find that it all interlocks

Columbus' first voyage into the unknown most certainly doomed to take more months than he had supplies, lucks out and discovers new continent

using the stars on a spherical sky as guide, we begin to map coastlines onto a globe, the coasts of Europe/Africa fit north/south America!

we find rock formations and fossils on both sides of the Atlantic that match each other.

we sound the entire floor of the Atlantic ocean and map its valleys and mountains, we find a ridge in the middle that matches both coastlines

this ridge is hot with fresh magma rising and cooling to basalt, forming new ocean floor

core samples all along the ocean floor, the bedrock is all basalt

the continental crust however is mostly granite with basalt inclusions and folded metamorphosed sediments it has a much more complex history

core samples along ocean floor have deeper and deeper layers of sediment on top as you get closer to the coasts, closer to the coasts is older?

when we discovered radioactive decay, we learned how to tell the age of REALLY OLD rocks. yup, the ocean bedrock is older towards the coasts.

but ocean bedrock is, over all, young, only a few hundred million years old, continents much older, some rock billions years old.


why not measure the magnetic orientation of rocks? it orients to the magnetic field of the earth when the rocks form from molten magma

in young bedrock, the magnetic field is oriented towards the poles, in older bedrock, not so, either the poles move or the bedrock moved!

map the magnetic fields across the ocean floor! on either side of the ridge, parallel matching stripes, flipping north, south, north, south...

the north and south poles were reversing orientation every few million years?

look at the magnetic orientations of older and older bedrock on continents, they all point to stationary poles if we MOVE the continents!

well? lets go and WATCH the continents, ARE they moving apart?  HELLS YEAH, umm... by half an inch per year.  this takes radio, or radar or satellites

but 1/2 inch a year is enough if you multiply it by the radio-dates of the oldest ocean crust, BINGO, you get the distance between the coasts!

can entire continents REALLY move? how many MORE INTERLOCKING measurements do you want before you are convinced?  this is how science works

half inch out of 3000 miles is like 1 part in 100 million.  to get these measurements to match we are measuring THAT accurately.  SCIENCE!

so, like soup in a pot, the entire earth is gyrating round and round in a series of interlinked convection cells, continents floating on top

theory of plate tectonics interweaves all the disparate phenomena of geology: continents, oceans, volcanoes, earthquakes, mountain building...
