Compact Disc (CD) is a digital optical disc data storage format. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CDs and audio CD players have been commercially available since October 1982.

Since the founding of Freemasonry, many Bishops of the Church of England have been Freemasons, such as Archbishop Geoffrey Fisher. In the past, few members of the Church of England would have seen any incongruity in concurrently adhering to Anglican Christianity and practicing Freemasonry. In recent decades, however, reservations about Freemasonry have increased within Anglicanism, perhaps due to the increasing prominence of the evangelical wing of the church. The former Archbishop of Canterbury, Dr Rowan Williams, appeared to harbour some reservations about Masonic ritual, whilst being anxious to avoid causing offence to Freemasons inside and outside the Church of England. In 2003 he felt it necessary to apologise to British Freemasons after he said that their beliefs were incompatible with Christianity and that he had barred the appointment of Freemasons to senior posts in his diocese when he was Bishop of Monmouth.
What English Archbishop was a member of the Freemasons?
****
The answer: Geoffrey Fisher

Another principal tool in the diagnosis of infectious disease is microscopy. Virtually all of the culture techniques discussed above rely, at some point, on microscopic examination for definitive identification of the infectious agent. Microscopy may be carried out with simple instruments, such as the compound light microscope, or with instruments as complex as an electron microscope. Samples obtained from patients may be viewed directly under the light microscope, and can often rapidly lead to identification. Microscopy is often also used in conjunction with biochemical staining techniques, and can be made exquisitely specific when used in combination with antibody based techniques. For example, the use of antibodies made artificially fluorescent (fluorescently labeled antibodies) can be directed to bind to and identify a specific antigens present on a pathogen. A fluorescence microscope is then used to detect fluorescently labeled antibodies bound to internalized antigens within clinical samples or cultured cells. This technique is especially useful in the diagnosis of viral diseases, where the light microscope is incapable of identifying a virus directly.
What is microscopy used for?
