Nocebo Or Placebo?
The Placebo effect is a largely known about phenomenon within
society despite our little scientific understanding of it. (I wrote this piece a while ago about it.) Though its reversal
the ‘Nocebo effect’ is not widely known about. Nocebo comes from the
Latin of ‘I will harm,’ the general principle behind it is there can be
undesirable or harmful effects when a patient takes a ‘placebo’ pill, one with
no active ingredients.

The Beauty And Science Of Water
Please like my Facebook page: The Blogging Skeptic
With all the snow disruptions hitting the UK I thought I would look at the science behind water.
Water is the most important chemical compound on our planet, it covers 71% of our planet and is vital for all life. Water is a covalently bonded polar molecule, with the oxygen being slightly negative and the hydrogen being slightly positive with hydrogen bonding between molecules.
The properties of H2O make it perfect for providing life. Water has a high latent heat of vaporisation which put simply means that when water becomes a gas it removes energy from the source of where the water was. So when animals sweat energy is removed from the body and homoeostasis is maintained. Also, water has a high specific heat capacity which put simply again means it takes a lot of energy to raise a kg of water by 1 degrees Celsius. This means that water remains at a fairly constant temperature in large amounts which is vital for ensuring life continues by the little variation in oceans and seas.

Looking Back...Science Highlights of 2012
2012 was certainly a great year in terms of science, as per usual many amazing advances in the scientific community were made. Here are some of the highlights...
1.) Probably the most famous in 2012 was the discovery of the previously theoretical Higgs Boson. Its discovery gave particle physics a great leap in knowledge and positively raised its awareness and educated the general public.
2.) Just above I said the discovery of the Higgs Boson was the most famous, I guess the next event is globally even more well-known about. In October, Felix Baumgartner skydived from the 'edge of space' and fell faster than the speed of sound. Despite some difficulty that he experienced he successfully completed the dive.

A Blogging Skeptic's Atheist Christmas
Only 6 days till…well
you know what. It’s Christmas! The awkward time of the year for atheists- the
decision whether to celebrate it is a sensitive issue for many atheists. It is
the balance between family, sentiment and personal objection to this religious
holiday that many find difficult.
Whilst some
object altogether about celebrating this holiday there are others who
celebrate what is becoming an increasingly secularised celebration. With
atheist participation in Christmas it highlights and increases the awareness that
this event is a somewhat secular holiday. Even if you don’t want to celebrate
Christmas per se, why not celebrate the fact it is a public holiday. Or make up
your own celebration- the birth of Richard Dawkins perhaps? Who cares if Dawkin’s
was born in March it makes perfect sense to celebrate it in December, after all Jesus wasn't born in December!
Now onto Tim
Minchin and his brilliantly crafted and intelligent exploration into a
Christmas for non-believers. Although this song was released in 2009, it never
ceases to fade in its magnificence and is still my number 1 Christmas song each
year. The song portrays Tim’s feelings about how
Christmas is still important to non-religious people and the sentient, along
with sharing time with your family is important.
Whatever your views and whatever holiday you will be celebrating, Happy Holiday and Merry Chri...HOLIDAY!- From The Blogging Skeptic

Derren Brown Part 2- Religious Experience
As promised,
here is my response to Derren Brown’s ‘Faith’ show. The shows are still on 4oD
if you wish to watch them.
In this
programme Derren Brown demonstrates how a ‘religious experience’ can be induced
on someone, in this case a stem-cell scientist and a strong atheist. It was a
fascinating show because Derren was not presenting full conclusive evidence for
the non-existence of God(s) but exploring that the belief in God could stem
from our humanistic needs and is hard-wired into us.
The concept
of a God was always going to be applied by humans to explain the world no
matter whether it was true or not, centuries ago humans knew very little about
the world around them and the need to be able to explain the world was
essential to the basics of living. As Derren showed in this programme we are
all susceptible to suggestions of a supernatural presence, in essence it is
hard wired into every one of us. He used several experiments on members of his
audience to demonstrate this. He performed a satanic ritual where the person
read out a satanic rite declaring their allegiance to Satan, out of an audience
consisting of mainly atheists, agnostics and skeptics only a few were willing
to perform it- 11 out of 160. As Derren after this said “we are all born with
an inbuilt hardwired tendency to believe,” and it was that niggling doubt in
the back of their minds that made them not decide to partake.

Derren Brown Part 1- Placebo Effect
In this post
and the next I am exploring Derren Brown’s ‘Fear and Faith’ shows. I am looking
at part 1, ‘fear’ which examines the placebo effect. The first show was
broadcasted on Friday 9th November, apologies for time delay. The
shows are still on 4oD if you wish to watch them.
In the
programme, at first Derren Brown reveals a drug ‘Rumyodin’ that inhibits fear;
it had been used within the U.S army and now they had the permission to use the
drug on a clinical level for a select few members of the public. After several
minutes he reveals that it is in fact a fake, the drug does not exist and it is
simply an elaborate façade for a placebo pill. Derren cleverly created the name
‘Rumyodin’ which is actually an anagram of ‘your mind.' After this
it shows Derren leading several people into Cicero’s (the fake company) medical
centre and the placebo effect has already begun with the professionalism of the
trials and the medical centre.

Church of England's Opposition To Women Bishops
Last week
the Church of England voted against the introduction of women Bishops. The
General Synod requires a two-thirds majority in the three houses (Bishops,
Clergy and Laity) to be able to pass a vote, in this case it failed to be
passed because 122 out of 324 members voted against it- 62% voted in favour for
this vote.
I read a
Telegraph article on this topic that went by the title ‘Swaziland has a woman bishop
– why not Suffolk?’ It
started with telling the story of how Ellinah Wamukoya became the first female
bishop in Swaziland with the Anglican Church of Southern Africa. People are
bemused at how a country like Swaziland which does not have a particularly good
reputation for being liberal is seemingly ahead of us in terms of liberal
development. Though it does appear to be ridiculous, this comparison does
really not have much relevance to the whole situation and it is probably fair to
say that this is one of the only things in which Swaziland is more liberal in- though
please do correct me if I am wrong.

Evolution vs. Creationism, Truths And Lies
I find it
horrifically sad that in this day and age people are still being allowed to corrupt
the educational system and brainwash children into believing in creationism.
Creationism
is the belief that a supernatural being created Earth, there are numerous
subgroups of creationism with further beliefs. I will be referring to the
creationism that is being taught in the place of science that opposes the
Darwinian theory of evolution.
In
the words of Tim Minchin, ‘Faith is the denial of observation, so that belief
can be preserved.’ The whole concept of creationism is the denial of truth when evidence is staring them in the face and somehow they still find it a
truthful concept to believe in without a shadow of doubt. Just like
water flowing from a tap, evidence for evolution is abundant. I am no expert on
Darwin’s theory of evolution yet I could easily reel off lists of what presents
evidence supporting it: Ontogeny recapitulates phylogeny, fossil comparisons,
DNA genetic sequences, pseudogene,
peppered moth evolution, the list goes on…

Alien vs. Ghost
I
sat down to watch the television several days ago only to find that a new
series of ‘Most Haunted’ was on, despite my strong opposition to psychic
mediums claiming they can communicate with the dead I decided to watch
it. I never realised how much of a comedy it was!
Getting
back on to the subject…I wanted to explore the believability of ghosts and
aliens and ask the question which are more believable? Aliens and ghosts are
two very ambiguous terms; I feel that when people hold a belief in aliens in
this context they are referring to an intelligent life form and not merely the
existence of single celled organisms. I would refer to a ghost as an apparition
of something that was once alive, whether it is a person or an animal.
People
like to believe in ghosts because they were once human and it gives them an
explanation to the afterlife. It requires no effort to visualise ghosts because
they represent the human form, whilst aliens require some imagination. This
still applies today, but would have been more relevant in past before the
portrayal of aliens in television and film.

Can Science Be Dangerous?
In society there
are a large number of people who question the safety of modern science and the
harm it can do. There are many reasons for this: one is rooted in television,
film and literature, you only need to think of Frankenstein and how a
scientific experiment can go ‘wrong.’ Some people simply lack the education and
their opinions are based on what they see and hear from inaccurate sources.
Media and history can have a significant widespread impact- for example fear on
anything nuclear related is primarily due to the atomic bombings of Hiroshima
and Nagasaki in 1945 and the events that happened in Chernobyl, 1986 and more
recently the Fukushima nuclear disaster in 2011.
Back to the
question, people often misunderstand what science is, so let me first define
it. For the purpose of this piece I have chosen a basic definition: “science is
knowledge attained through study or practice.” So science is a body of knowledge,
it tells us how the world is, based upon scientific research conducted. On its
own knowledge is perfectly safe and has no moral value but the point at which
science can become dangerous is when science (or knowledge) is applied through
technology.
Technology
means applying knowledge to create something and I think the beauty of science
is often overlooked; science is not about creating a product or tool to achieve
a purpose or solve a problem however it is the collecting of facts and data from
a systematic approach which then leads to further knowledge and thus can be
used to help create technology.

Death Through The Eyes Of A Skeptic
With these blogs I will not shy away from any relevant topics and today I have decided to tackle death and cover my views on death and the afterlife (or the lack of one.)
My views on death have been shaped through my atheism, skepticism and through science. My atheism does not command me that there is no afterlife, because what atheists share is the lack of belief in gods so it is therefore possible to have an atheist who believes in some form of the afterlife. But what primarily convinces me is due to the fact that there is no empirical evidence to suggest is it true.
A common misconception that believers in the afterlife think is that because non-believers hold the belief that there is not an afterlife, their life is somehow meaningless or irrelevant. On the contrary, in my view because there is not an afterlife surely life becomes more meaningful. Your existence has a time frame, it is not this never ending eternity we are taught about. This gives me the mindset that surely I should try and do productive things in my life and enjoy it as it is all I have.

A Warm Welcome & Introduction
Hello and I would first like to thank you for reading this post. Let me introduce this blog with a little bit about myself. I am a 16 year old who attends college and spends a lot of time thinking about the world. My understanding of the world is shaped through my logical, rational and skeptical thinking and I believe valid judgements can only be made with scientific and empirical evidence and not merely through the application of faith and religion. I am young, curious and still have a lot to learn, but I want to share my thoughts and views with as many people as I can.
As the sub title says this blog will cover topics on atheism, skepticism and science, these are extremely broad subjects which allows for an open and diverse blog. Each week I will post a blog discussing a question, topic, news piece or something which I feel is relevant and it will be available every Wednesday morning. I aim to make this blog not just simply me expressing my views but a community where everyone can share their opinions as well. So feel free to comment on posts, whether you disagree, want to share an alternative view or offer feedback, please do. I thought I would keep this post short and to the point but the weekly blog will have more depth and substance to it.
