OK, I can not, not write about this. The 'Duck Boat' accident in the US.
This rolling/motoring deathtrap had 33 people on board, killing 17, including 9 members of ONE family....
All I can think of, each time i go to a news site and see the headlines is, 'This company is DEAD. They are gonna be sued into the Earth, no matter what waivers, IF, any'
I mean WHY the FUCK would the operators go out? One answer... M O N E Y.... They got the 33, or maybe less if some were crew, people's money.... Albeit, many witness' say it was "calm" when that death trap went into the water, apparently there were major weather reports that a storm was coming. I mean, you look at the video they have around of "the last seconds before disaster struck" and it's fuckin' chaos on the water. NO one in their right mind would have continued on, turn that shit trap around and get those people back to safety, run the emergency up the poll and get those guests in life jackets, I mean christ, the kids must've been frightened to ... well.... Sad, sad, I'm reading reports that the governments been saying for years these are death traps, but they were still out there.
Some figures say that 33 people have died in the last 10/20 years in those things, whether on dry land or in the water and because of those deaths, those companies died.
Pretty fucked up situation and a lot of peoples lives have just changed and again, all for the love of money....
This afternoon, while coming out of my neighbours with some laundry, one of the little chipmunks was quite close to my stairs, since yesterday, it's been getting closer and closer. Even closer than I got with Chippy, who've I've not seen since I called him a 'fat ass' the other day... Maybe he's hooked up on a Jenny Craig program or at the gym....
Anyhow, so, this little one, got super close, took a peanut I had on the ground and then I shook the other peanut that I had in hand and it came right over, cautiously, it took the peanut right from my hand! Success!
Was such a cute moment. I turned around to see that a random dude was walking past our driveway at the time this happened, he had a big grin on his face, as he must have just seen what went down.
So, once I do this a few more times, then I'll bring in the camera. I figured it would take a lot of patience and time for this sort of thing to happen. It's paid off.
One of my favorite areas of 'research' is in consciousness, the brain, neurons and how it all works. A lot of it, is beyond my brain, but I try. I still read and get the words in MY brain, in hopes I'll understand at some point.
Yesterday there was a fantastic article on Science Alert.com... The Huemahn brain can creeate structures in up to "11 dimensions".
Read on brave friends!
The Human Brain Can Create Structures in Up to 11 Dimensions
"We found a world that we had never imagined."
SIGNE DEAN 21 APR 2018
(Sciencealert.com) - - Last year, neuroscientists used a classic branch of maths in a totally new way to peer into the structure of our brains.
What they discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions.
We're used to thinking of the world from a 3-D perspective, so this may sound a bit tricky, but the results of this study could be the next major step in understanding the fabric of the human brain - the most complex structure we know of.
This brain model was produced by a team of researchers from the Blue Brain Project, a Swiss research initiative devoted to building a supercomputer-powered reconstruction of the human brain.
The team used algebraic topology, a branch of mathematics used to describe the properties of objects and spaces regardless of how they change shape.
They found that groups of neurons connect into 'cliques', and that the number of neurons in a clique would lead to its size as a high-dimensional geometric object (a mathematical dimensional concept, not a space-time one).
"We found a world that we had never imagined," said lead researcher, neuroscientist Henry Markram from the EPFL institute in Switzerland.
"There are tens of millions of these objects even in a small speck of the brain, up through seven dimensions. In some networks, we even found structures with up to 11 dimensions."
Just to be clear - this isn't how you'd think of spatial dimensions (our Universe has three spatial dimensions plus one time dimension), instead it refers to how the researchers have looked at the neuron cliques to determine how connected they are.
"Networks are often analysed in terms of groups of nodes that are all-to-all connected, known as cliques. The number of neurons in a clique determines its size, or more formally, its dimension," the researchers explained in the paper.
Human brains are estimated to have a staggering 86 billion neurons, with multiple connections from each cell webbing in every possible direction, forming the vast cellular network that somehow makes us capable of thought and consciousness.
With such a huge number of connections to work with, it's no wonder we still don't have a thorough understanding of how the brain's neural network operates.
But the mathematical framework built by the team takes us one step closer to one day having a digital brain model.
To perform the mathematical tests, the team used a detailed model of the neocortex the Blue Brain Project team published back in 2015.
The neocortex is thought to be the most recently evolved part of our brains, and the one involved in some of our higher-order functions like cognition and sensory perception.
After developing their mathematical framework and testing it on some virtual stimuli, the team also confirmed their results on real brain tissue in rats.
According to the researchers, algebraic topology provides mathematical tools for discerning details of the neural network both in a close-up view at the level of individual neurons, and a grander scale of the brain structure as a whole.
By connecting these two levels, the researchers could discern high-dimensional geometric structures in the brain, formed by collections of tightly connected neurons (cliques) and the empty spaces (cavities) between them.
"We found a remarkably high number and variety of high-dimensional directed cliques and cavities, which had not been seen before in neural networks, either biological or artificial," the team wrote in the study.
"Algebraic topology is like a telescope and microscope at the same time," said one of the team, mathematician Kathryn Hess from EPFL.
"It can zoom into networks to find hidden structures, the trees in the forest, and see the empty spaces, the clearings, all at the same time."
Those clearings or cavities seem to be critically important for brain function. When researchers gave their virtual brain tissue a stimulus, they saw that neurons were reacting to it in a highly organised manner.
"It is as if the brain reacts to a stimulus by building [and] then razing a tower of multi-dimensional blocks, starting with rods (1D), then planks (2D), then cubes (3D), and then more complex geometries with 4D, 5D, etc," said one of the team, mathematician Ran Levi from Aberdeen University in Scotland.
"The progression of activity through the brain resembles a multi-dimensional sandcastle that materialises out of the sand and then disintegrates."
These findings provide a tantalising new picture of how the brain processes information, but the researchers point out that it's not yet clear what makes the cliques and cavities form in their highly specific ways.
And more work will be needed to determine how the complexity of these multi-dimensional geometric shapes formed by our neurons correlates with the complexity of various cognitive tasks.
But this is definitely not the last we'll be hearing of insights that algebraic topology can give us on this most mysterious of human organs - the brain.
The study was published in Frontiers of Computational Neuroscience.
