This month AW #42 named "Countertop Geology" by Ian Saginor of the blog  Volcanoclast. Have you seen a great countertop out there?

Our funny crew showing broken carbide bit after a troubles while drilling in a hard dolomite in North Sinai, Egypt in a mission to reach the Nubian aquifer. http://youtu.be/KhTy0UoVa40 Drilling on earth have a lot of problem, I wonder what kind of machines and equipment we need to drill on the Mars in case of exploring for groundwater? :) http://youtu.be/6sk5IuIjr1E

In response of Anne Jefferson questions for Accretionary Wedge #38 : If you are a current or future student… what do you want to know about life and careers in the geosciences? Are there things you aren’t getting to learn or do in classes that you think are important? What sort of experiences do you want to get out of school and how do you think school can or should help you prepare for a career? My respond here focus on, the method of studying geology. It's helpful to study how particular branch of geoscience are developed, like how continental drift theory are become the most accepted theory, but it's not necessary to study how seismic investigation are developed thorough the time. Students need to know how to interpret a seismic section; not to know who developed that branch of science so the large introductions of any subject in collage is like wasting the time. How is this branch of science work? why it useful? and how can i use it? that what i think is  important in stud...

How is the web changing science? Join Science Online London 2011 to find out. My brain tried to find out that with others on twitter the best brainstorming online tools on web. I tweet a lot of thoughts, and questions about science blogging and science policies during the live stream . And here is some of the problem that I'm interested in it. Personally i hate speaking on behalf of employers or organizations, I hate that fear of say something unprofessionally, specially when you wondering or blogging about your job or your career. You know that style of speaking/blogging "I'm awesome and my employer/organization is the best" we say that, because we don't want to loss our jobs.

Mushrooms Image via Wikipedia The White Desert is located at the northern region of the Farafra Oasis . I had visited it within field trip to western desert. The white desert has been classified by government of Egypt as a natural protected zone in 2002 and covers an area of 3010 square kilometers. It's far 570 km from Cairo. The White desert is a unique geological phenomenon; where wind and water erosion sculptured their way through the soft chalk forming incredible shapes "Mushrooms". Along the road Baharia - Farafra, the main geological observations as many isolated hills and hillocks consisting almost of massive bedded, snow white chalk of Maastrichtian Khoman Formation. There are many fascinating geomorphologic feature accompanied the carbonate rocks of the plateau surface such as cave deposits and onyx,

There was some questions in my mind when i start my blog, How to make a good blog? How to blog? What is the best style for science blogging? I got some good answer lately, I think it's useful enough to share it here with sci bloggers who want know the answer or have answers of the following questions. What is the best blogging service for scientists (Blogger, Wordpress, tumblr, or Posterous etc.)? Obbie King : The best blog for a scientist (or anyone, for that matter) is the one that that particular person finds most comfortable to work with and that most effectively communicates the content he/she is presenting. I would suggest "playing around" with some of the more popular platforms, look for ways to make it "look" the way you want, and decide which platform makes you feel more comfortable. You then may wish to get help from someone who's well-versed in your chosen service to set up the fine details and get you rolling.

Aquifers Properties: Specific Yield and Specific Retention In an aquifer with a water table (unconfined aquifer), the volume of water released from groundwater storage per unit surface area of aquifer per unit decline in the water table is known as the specific yield, S y . also known as the drainable porosity. Hydrologists divide water in storage in the ground into the part that will drain under the influence of gravity (called specific yield) and the part that is retained as a film on rock surfaces and in very small openings (called specific retention). The physical forces that control specific retention are the same forces involved in the thickness and moisture content of the capillary, fringe. fig.1
