The Creation of Adam


The Creation of Adam is a section of Michelangelo's fresco Sistine Chapel ceiling painted circa 1511. It illustrates the Biblical story from the Book of Genesis in which God the Father breathes life into Adam, the first man. Chronologically the fourth in the series of panels depicting episodes from Genesis on the Sistine ceiling, it was among the last to be completed. 

Composition 
God is depicted as an elderly bearded man wrapped in a swirling cloak while Adam, on the lower left, is completely naked. God's right arm is outstretched to impart the spark of life from his own finger into that of Adam, whose left arm is extended in a pose mirroring God's, a reminder that man is created in the image and likeness of God (Gen 1:26). Another point is that Adam's finger and God's finger are not touching. It gives the appearance that God, the giver of life, is reaching out to Adam and Adam is receiving. The pink backdrop behind God is in the shape of a brain. Michelangelo may have used this symbol to show God's plan of creation which had not yet been revealed to the first man.
The inspiration for Michelangelo's treatment of the subject may come from a medieval hymn called Veni Creator Spiritus, which asks the 'finger of the paternal right hand' (digitus paternae dexterae) to give the faithful speech, love and strength. 

Anatomical theories  
Several hypotheses have been put forward about the meaning of The Creation of Adam's highly original composition, many of them taking Michelangelo's well-documented expertise in human anatomy as their starting point. In 1990 a physician named Frank Lynn Meshberger noted in the medical publication the Journal of the American Medical Association that the background figures and shapes portrayed behind the figure of God appeared to be an anatomically accurate picture of the human brain, including the frontal lobe, optic chiasm, brain stem, pituitary gland, and the major sulci of the cerebrum. Alternatively, it has been observed that the red cloth around God has the shape of a human uterus (one art historian has called it a "uterine mantle"), and that the scarf hanging out, coloured green, could be a newly cut umbilical cord.

Bhuvan mapping

DOWN LOAD Bhuvan mapping A review of ISRO Bhuvan Features and Performance

Here is a frank review of the features and performance of ISRO Bhuvan (the much anticipated satellite-based 3D mapping application from ISRO) BETA Release and comparing it to supposed arch rival Google Earth. Bhuvan from the begining is claiming that it is not competing with Google Earth in any way, but there was much hype and propaganda in the media saying that ISRO Bhuvan will be a Google Earth killer atleast in India. But it looks like that can nit be the case anytime soon. Here is why..

  • While Google Earth works on a downloadable client, Bhuvan works within the browser (only supports Windows and IE 6 and above).
  • The ISRO Bhuvan currently has serious performance issues. The site currently very unstable. It gives up or hangs the browser every once in a while. When a layer (state, district, taluk, etc.) is turned on, it renders unevenly and sometimes fails to render at all. The navigation panel failed to load routinely and it felt like a rare sighting when we could actually use the panel.
  • The promise of high resolution images has not been kept. While the service promises zoom up to 10 metres from the ground level as against 200 metres for Google Earth, we didn’t encounter a single image with nearly as much detailing. In fact, comparative results for a marquee location such as New Delhi’s Connaught Place or Red Fort make its clear as to the inferior performance of ISRO Earth as of now.
  • The navigation tools are similar to Google Earth (GE).
  • The search doesn’t work if a query returns multiple results. A pop up window is supposed to give the multiple results from which the user is supposed to be able to choose. During two days of sporadic testing, we found the result only once. The rest of the time, the window would pop up, but nothing would be displayed. When the search is accurate, the software ‘flies in’ to the exact location, the same way as GE.
  • Users need to create an account and download a plug-in.
  • Bhuvan packs a lot of data on weather, waterbodies and population details of various administrative units. We were unable to access weather data. Clicking on icons of administrative units show basic information such as the population. For specialist users, Bhuvan might hold some attraction. For instance, there is a drought map which cab be used to compare drought situation across years and there is a flood map that shows Bihar during the Kosi flood and after. With Isro backing, Bhuvan would be able to provide such relevant data from time to time, but the application needs major improvements in terms of usability before it will be of interest to the ordinary user.
  • Users can also not edit any data or tag locations.
  • We hope Bhuvan is able to fix the bugs soon. But even then, to be a credible alternative to existing mapping services, and even to get new users to try it, it much provide much higher resolution images. User interest will be piqued only when they can see their house or school or local street in high resolution. With Isro data, this is easily doable.

Having said all this, ISRO Bhuvan is still a very good step forward for ISRO in the right direction we feel. We wish all the best for ISRO and hopefully Bhuvan will mature very fast to become a good service and can really compete with Google Earth.
