Spring Equinox

March 20th, 2008

Today (in the UK at least) marks the spring (vernal) equinox, with the Earth at zero tilt, and the Sun crossing the celestial equator at zero declination. Having purchased a Tal-1  last week, I managed to catch some very clear views of Saturn, above a fall moon last night…being the second time I’ve used this telescope, it was a very pleasing sight.

ELQ funding phased out

February 21st, 2008

Yet more funding disappointment, as the HEFCE ‘Higher Education Funding Council for England’ has declared it will phase out ELQ ‘Equivalent or Lower Qualifications’ funding.

This will prevent potential students receiving financial help towards any course they wish to take, that is equivalent to or lower than any previous qualifications they may hold, regardless of subject.

£ 30,000,000.00 will be withdrawn from ELQ funding commencing this year.

This clearly stifles anyone wishing to study a different subject, who are unable to meet the high costs of further part-time education. To put things in perspective, I’m currently at first year under-grad level, and the costs without financial support would have been approximately £ 1,700.00 to date. With pitiful pay rises over the last few years, it’s unlikely I could have met these costs. For people in more financially constrained situations, the idea of further education, would not even be worth considering.

The only exceptions are disabled students, and students from Northern Ireland. Vice Chancellor, Professor Brenda Gourley of the OU reported…

It is with a combination of frustration and disappointment that we note the outcome of the consultation by the Higher Education Funding Council for England into the withdrawal of funding for equivalent or lower qualifications.”

“It is reassuring to note some of the decisions of the HEFCE board, including consideration to be given to the idea of exempting students who receive the Disabled Students Allowance. In addition, the decision that Open University students studying in Northern Ireland will not be affected by the funding changes answers the OU’s call for these students to be treated in the same way as ELQ students at other institutions in Northern Ireland.”

“However, it is disappointing to see that – notwithstanding the decision to review annually the list of subjects for which ELQ students will be funded – some subjects for which the University has suggested ELQ funding continues remain omitted from the list of exemptions; they include ICT and computing. Equally compelling cases for extending exemptions to include specific groups of students, such as those on low incomes or women returning to work after caring responsibilities, have not been accepted by the HEFCE Board.”

“It is, furthermore, the fundamental principle of the funding changes for ELQ students – rather than the implementation of the changes on which the funding council was consulting – that remains of most concern. The new policy discourages students from upskilling or reskilling, and it discourages institutions from catering to them. The negative impact on individuals and their career development, on institutions and on the wider economy remains of particular concern.”

“The lack of consultation before the announcement of the changes some six months ago also remains a major concern; consultation merely on the implementation of the changes was far from sufficient.”

Physics tutorial…LaTex ?

February 19th, 2008

On completion of my first assignment, I will be populating this category with a physics tutorial that will start with the basics of kinematics, through to QM, and will be updated as I progress through my degree.

I will be adding footnotes, and when appropriate diagrams, which may help in visualizing the maths, and familiarize the reader with new concepts. I’m also going to avoid using yawn inducing situations, such as describing the motion of a car, off a ramp. Instead, expect situations such as, the motion of a rabid chinchilla, on a jet propelled scooter, off a ramp. First things first, just testing to see if LaTex is recognised…

M_{pl} = \sqrt\frac{h c} {2\pi G}

Thanks to Klaynos for the advice.

Bah !

February 8th, 2008

The withdrawal of the UK involvement with the ILC has been confirmed, along with UK astronomers denied access to the two Gemini telescopes in Chile and Hawaii, despite the UK as founding members.

A massive blow to the field of physics in the UK, and if the trend continues, I will certainly be seeking opportunities outside of Britain, at the end of my education.

Math stress

February 7th, 2008

If you’re like me, and sometimes start pulling your hair out with frustration on a math problem, simply think back to all the other times you started pulling your hair out with frustration on a math problem…the frustration may turn to a chuckle. Or it may turn into a trip to the off license, either is better than a bald scalp.

Also, when that light bulb pings on and the problem falls into place, all that frustration was vented on something that appears painfully obvious, a missing piece of a collection of painfully obvious pieces…why else would it prompt ‘of course!’ followed by ‘why didn’t I see that before!’

Red shift distortions

February 7th, 2008

Fascinated by any developments on the mapping / modelling of cosmic expansion, I found yet another technique which goes back to measuring red shifts of galaxies as opposed to type 1a Supernovae, but with a twist. This time the distortions generated by the motion of galaxies on red shift measurements, e.g local gravitational effects from neighbouring objects, and comparing the data at different epochs (distant and nearby galaxies), is an idea proposed by European astronomers.

from physicsworld…

Measuring galaxy distortions is not new in itself, but by doing so at different cosmic epochs researchers may be able to learn more about the cosmic acceleration. “A discrepancy between the amount of distortion at different times would be a smoking gun for a new theory of gravity,” says Luigi Guzzo of the Brera Astronomical Observatory in
Italy

First isolated GRB sighting ?

February 7th, 2008

On the 25th of January last year, the first visibly isolated GRB, namely GRB 070125 was detected by the Inter-Planetary Network. Following the sighting of a ‘fast-fading’ after glow from the Palomar Observatory in California, further analysis was conducted using the Gemini North and Keck telescopes in Hawaii. This revealed no absorption of light from dense gas or dust surrounding the GRB, and was later confirmed when the glow had faded…there was no sign of a galaxy.

The next step is to take a long exposure shot using the Hubble Space Telescope, to confirm if the star formed in a ‘tidal-tail’ which make up 1% of star formations in our local universe.
