Carbon 14 – How It Is Used To Date Objects

All living organisms have carbon in it. Carbon-14, a radioactive carbon component is also found in all living organisms in small quantities. By using this radio active component, scientists can easily determine the age of clothing and wood and anything that once lived or was alive. The method used to date any object with the help of carbon-14 in that organism is known as ‘radiocarbon dating’.

This technique commonly known as carbon-14 dating can be used to date objects as old as 50,000 years. All radioactive elements break down and the rate at which these radioactive substances break down is known as half-life. An objects half-life is the time that has been taken where half of the objects atoms breaks down.

Carbon-14 has a half-life of about five thousand five hundred years. If we do our maths right we can easily determine the exact date of death of an animal or plant or any object for that matter. In 5,500 years, half of the carbon-14 atoms originally present at the time of the death are present or half of the carbon-14 atoms had broken down.

Thus after eleven thousand years one-fourth(1/4th) of the carbon-14 atoms are left and after sixteen thousand five hundred years(16,500), one-eights(1/8th) of the original carbon-14 atoms are left. The calculation goes on and this is the reason we can estimate the age of any item up to 50,000 years. The actual dating of any object is done in a laboratory.

For example a piece of wood which is very old is found in an ancient tomb. This is brought to the lab and is heated and converted into carbon or it is burned which produces various types of gases that includes carbon dioxide. These carbon dioxide or carbon has few carbon-14 atoms that are breaking down constantly.

With every break down, a very minute particle is sent speeding out of the atom. The carbon dioxide or carbon is placed in a very sensitive instrument which is known as ‘Geiger Counter’. This instrument detects these particles which are exiting at high speeds i.e. it detects the carbon-14 atoms that are given off.

Scientists can determine the amount of carbon-14 left in an object by calculating the number of particles given off with the help of the Geiger counter. Similarly scientists can also determine the carbon-14 which is contained in a small piece of wood acquired from a living tree. But this technique is used for determining the age of ancient objects.

From the amount of carbon-14 left, scientists determine the age of the object. If half the amount of carbon-14 is left, then it means that the object is 5,500 years old. Scientists also use this technique to date the age of trees in rain forests so as to conserve them from further destruction by the human race.

Aeronautical Engineering As A Career Option In India

Aerospace or Aeronautical engineering is one of the divisions of engineering which a candidate can
specialize in. It is one of the most diverse and challenging career options and deals with technology and
research in the field of defense systems, space exploration and aviation.

One can find career options relating to maintenance and operation of missiles, spacecrafts and commercial and military aircrafts and also design, build prototypes, develop and test and be involved in extensive research and development in the above fields. Teaching is also an important career option in aeronautical engineering.

To take up aeronautical engineering as a career option, one needs to have aptitude for mathematics as
precision is vital in this field. Also one needs to possess technical knowledge and be good with computer systems.

Aptitude for manual and mechanical work is also required to gain success in this field. A
successful career in this field requires high energy levels with an eye for details as the job can get very
demanding when it comes to operations and maintenance and in the research line, one has to meet
deadlines with efficiency and precision.

To start a career in this field, a B.E. or a B.Tech degree is required or a diploma course at least needs to
be completed. There are many institutions in India which offer this program namely the IIT’s, Hindustan
college of Engineering, Punjab Engineering College, etc. The basic eligibility criteria to get selected into
these colleges would be a 10+2 education majoring in maths, physics and chemistry. To get selected
into the IIT’s, a candidate has to take up the Joint Entrance Exam (JEE) and selection is based purely on merit.

For gaining entry into the rest of the colleges, common entrance exams are conducted and selection is
based on the marks secured in 12th standard and the candidate’s performance in the common entrance
test. Few institutions also offer M.Tech and Ph D programs in this field, namely IISC, etc. There is also a
distance education program available for working professionals and diploma holders to gain a B.E
degree. This is conducted by ‘The Aeronautical Society of India’ whereby the candidates study through
distance mode and appear for the AMIE(Associate Membership Examination of the Institute of
Engineers) exam to gain the B.E. degree

.
Aeronautical engineers are highly paid officials, both in the public and private sectors. In the public
sector, graduates can get jobs in DRDO, ISRO, HAL, NAL, defense research and development
laboratories, Aeronautical Development Establishments, defense services and the civil aviation
department. In the private sector, private airlines employ such graduates.

Hair Restoration: Reasons and how one can help himself

There are various things that start changing in our body as we step into the teenage and go across with it. Also, one very vital factor is that all the changes that were experienced by a human being are now taking place at a more tender age for both boys and girls.

Education is the process of facilitating learning. Knowledge, skills, values, beliefs, and habits of a group of people are transferred to other people, through storytelling, discussion, teaching, training, or research. Education frequently takes place under the guidance of educators, but learners may also educate themselves in a process called autodidactic learning. Any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.
