What if there is a density of reality in which time is 3 dimensional? According to some types of String Theory, what you do right NOW can potentially cause what happened 5000 years ago in our interaction with linear time, because what we do to an electron effects both its past and its future according to string theory. We experience linearity, but what if time progression was nothing more than a series of universal cause-effect relationships randomly interconnected throughout time as a whole?

Compile Python 2.7 on CentOS
CentOS doesn’t have Python 2.7 by default, so if you want/ need to install it, this is what you do:
su
yum install tk-devel tcl-devel
yum install expat-devel db4-devel gdbm-devel sqlite-devel zlib-devel bzip2-devel
yum install openssl-devel ncurses-devel readline-devel
yum install git gcc
wget http://python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2
tar xf Python-2.7.5.tar.bz2
cd Python-2.7.5
./configure --prefix=/usr/local
# Always use Alt-Install !
# otherwise, you will overwrite Python 2.6 installation and your system WILL crash
make && make altinstall
# This will take some time...
# Test python 2.7
python2.7
Python 2.7.5 (default, May 31 2013, 14:00:00)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
Ok, now installing Distribute, the main Python package manager. It’s very important to have!
wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.tar.gz
tar xf distribute-0.6.tar.gz
cd distribute-0.6
python2.7 setup.py install
# You could also install PIP, but current version (1.3) doesn't work at all.
# So you can either install version 1.2 manually, or wait for a bug fix.
If you need to install Python compiled libraries, this is how you do:
# Install LXML parser
yum install libxslt-devel libxml2-devel
easy_install Cython
git clone git://github.com/lxml/lxml.git lxml
cd lxml
python2.7 setup.py build --with-cython install
python2.7 -c "import lxml"
# Install My Sql Python client
yum install mysql-devel
curl http://superb-sea2.dl.sourceforge.net/project/mysql-python/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz | tar zxv
cd MySQL-python-1.2.3
python2.7 setup.py build
python2.7 setup.py install
python2.7 -c "import MySQLdb"
Alternatively, you can try to install Python from a repository:
# Download and import the rpm gpg key
cd /etc/pki/rpm-gpg/
wget -q http://springdale.math.ias.edu/data/puias/6/x86_64/os/RPM-GPG-KEY-puias
rpm --import RPM-GPG-KEY-puias
# Create the repository file as /etc/yum.repos.d/puias-computational.repo
vim /etc/yum.repos.d/puias-computational.repo
# :: Paste this ::
[PUIAS_6_computational]
name=PUIAS computational Base $releasever - $basearch
mirrorlist=http://puias.math.ias.edu/data/puias/computational/$releasever/$basearch/mirrorlist
#baseurl=http://puias.math.ias.edu/data/puias/computational/$releasever/$basearch
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-puias
# Confirm the repo is functional
yum repolist | grep -i puias
# * PUIAS_6_computational: puias.math.ias.edu
# * PUIAS_6_computational PUIAS computational Base 6 - x86_64
# Check Python 2.7
yum search python27
Hope this helps!
