Pyritic nelsonite from the Precambrian of New York State, USA.
Nelsonites are scarce intrusive igneous rocks. They are also known as FTP rocks, in reference to their composition: iron-rich (Fe), titanium-rich (Ti), and phosphorus-rich (P). Nelsonites are principally composed of dark gray to blackish, metallic-lustered magnetite (Fe3O4) and ilmenite (FeTiO3) (or ilmenomagnetite; titanian magnetite), plus apatite (CaPO4). Minor minerals reported in nelsonites include spinel, olivine, pyrrhotite, and graphite. These rocks typically occur as Fe-Ti-oxide concentrations in anorthosite complexes. They appear to form as cumulates in cooling batholiths.
The sample seen here is from a nelsonite body, interpreted as an igneous dike, in Port Leyden, New York. This occurrence was first identified in the 1990s but the rocks were mined as iron ores in the late 1800s. Early mineral descriptions of the iron ore were inaccurate. Modern analysis by Darling & Florence (1995) has shown that Port Leyden nelsonites have 32-43% magnetite, 30-45% apatite, 8-15% ilmenite, and 5-11% iron sulfide (= brassy gold colored areas in the rock). Minor and trace minerals include chlorite, garnet, molybdenite, monazite, siderite, sphalerite, and zircon.
The nelsonite rocks at Port Leyden are black-colored, heavy, and extremely hard. Crack samples are very difficult to obtain - whacking with geology hammers usually results in small chips spalling away. Small pyrite patches and veinlets occur in the nelsonite.
I keep this specimen in a cup holder in my vehicle. It's an attractive, black-with-gold-specks, metallic-lustered rock. I'm probably the only person on the planet that drives with nelsonite at arm's reach.
Locality: waste rocks around old, flooded iron mine shaft, just south of North Street on the eastern side of the town of Port Leyden, just west of the Black River, western Adirondacks, southern Lewis County, north-central New York State, USA (~43° 35’ 05.47” North latitude, ~75° 20’ 27.28” West longitude)

The computerized Gait scan along with a thorough bio-mechanical analysis of your feet by your Physiotherapist is the only appropriate method that allows for a precise prescription of your custom functional orthotics. A 3D imprint of your foot is taken by the pressure sensors in the gait platform which gives your orthotic not only the perfect shape needed but also the timing to make it a DYNAMIC (walking) supportive device.

This is an image of a derelict house with large street art graffiti on the front which is an elderly person with their head in their hands. In the foreground, there is the house itself with the graffiti image over the middle window. In the background, there are multiple tall skyscraper offices/flats that are completely identical. The focal point is definitely the house as it is dominating the image therefore catching your eye. I think the colours and tones of this image are intended to reflect the mood as they are very dull and lifeless.
As this is a digital, colour image and by looking at the new buildings in the background a relatively modern photograph, I would expect this image to have been taken on a digital/DSLR camera as it is well-focused. I definitely think the photographer used a tripod due to the angle of the image which is rather abstract and may have been difficult to shoot free hand. I think JR has used good depth of field in this image which again shows how the main focus is on the house in the foreground.
The atmosphere created in this photo is very mundane due to the dull colours and content of the image. I think the photographer had this intention to make me feel this way as I think the image has a negative meaning to make you feel uncomfortable or to make you think about the reality of the topic. The mood of this image definitely helps the photographer portray the meaning as it has many representations in the image eg. The derelict house to the skyscrapers.
I think the image is showing how society has become much more capitalized due to the vast amount of new skyscraper buildings that are being produced and sold at extortionate prices. This is portrayed through the angle of the camera showing the traditional but decrepit house with the modern building looming over it in the blurred background. I think the meaning of the graffiti is to highlight how elderly people that have experienced the previous generations are very ashamed of us as we as a whole, support the idea of capitalizing the world. I think JR definitely had these intentions as they wanted to address the sometimes ignored topic and show how our society has conformed to revolutionizing our way of living instead of actually stopping and enjoying life itself.
This image has been taken by JR who is a photographer and graffiti artist. JR's work combines art and action and deals with commitment, freedom, identity and limits. This image was taken around 2011 in France. I think my view on the meaning of this image definitely coincides with the photographer as JR is known for using photography to address social issues in the world at the time which for this image would be the capitalist movement. This image was presented at an exhibition in Paris along with other images from the ‘Inside Out’ series which I think helped convey the message as there were more images to push the meaning forward.
I am studying this image in my project for ‘Discovery and Transformation’ as it links with my theme idea of discovering locations and looking more in depth about what is around you and at how one cultured area can have a vast different to another place and culture in this case, London and France. This image has helped me create new ideas for my project as it has made me think about incorporating social issues in the place I’m shooting into my images to help convey a stronger message.
Day one hundred seventy-four/365. I love academia. I feel fulfilled when I'm learning and I love to teach others.
But, I also realize that critical thinking has its limits. Sometimes, we run the danger of "paralysis by analysis."
I just read an article about the Massachusetts Institute of Technology. Some amazingly gifted people are students there.
But, the school has a requirement that's a special challenge for some of their most intelligent students. They require their graduates to know how to swim.
The author said that about half of the students jump in the water and get the swimming requirement out of the way early in their college career. Another percentage procrastinate. Some are afraid of the water. And when trying to learn to swim, people who are so gifted at math and engineering sometimes ask questions. At what angle should their arms enter the water? How far does one need to turn the head to get a breath without getting water in one's mouth?
Life guards find it difficult to convince some students to get in the water and just try it.
What things do we people of non-MIT material tend to over-think? What decisions are committees handling that could be completed more quickly and effectively by people who are willing to jump in the water and just try?
Thesis Data Analysis is not just the act of analyzing data with the help of statistical tools and application of a few tests. It is the complete process, starting with data collection, to data cleaning and arrangement. It ends with the interpretation of the results of the tests and simplification of the same for presentation.

The SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) Centre, is a “third-generation” synchrotron light source in Allan, Jordan, near Amman. The synchrotron facility is the Middle East’s first major international research centre for science applications. It is set for inauguration on 16 May 2017.
The Centre will focus on fostering innovative scientific and technological research in subjects ranging from biology, archaeology and medical sciences through basic properties of materials science, physics, chemistry, and life sciences.
The IAEA provides significant support to the Sesame project in training and sharing expertise, as well as facilitating the networking of SESAME staff with other global research facilities, thus enabling possibilities for scientific exchanges.

Part of an exhibition in a small museum in Madrid analyzing public spaces and plazas throughout the city. It looked at how useful the space was in sociability and design. This one got its fair share of use from people of the "Four Worlds"; homeless, prostitutes, etc..
