  4. CERN and its changing accelerator landscape SPS: 76  UA1/UA2: 81  90 LEP (Aleph, Delphi, L3, Opal): 1989  2000 LHC: 2009  2014 2010 2006 2002 1998 1994 1990 1986 1982 1978 1974 • I experienced: • PS/ISR, SPS, LEP, LHC • And, of course, the construction periods in between

  5. Changing Nobel prize rules SPS: 76  UA1/UA2: 81  90 LEP (Aleph, Delphi, L3, Opal): 1989  2000 LHC: 2009  2014 2010 2006 2002 1998 1994 1990 1986 1982 1978 Rubbia/van der Meer Englert/Higgs Charpak • 1984: Awarded to experimentalist • After discovery at CERN • 2013: Awarded to theoreticians • After discovery at CERN

  6. Computer Centre Changes SPS: 76  UA1/UA2: CDC, IBM LEP: IBM/Fujitsu, CRAY, RISC LHC (Prep+Run) : PCs  2014 2010 2006 2002 1998 1994 1990 1986 1982 1978 1974 Rubbia/van der Meer Englert/Higgs • Supercomputer/mainframes • CDC/Cray, IBM/Fujitsu • RISC workstations • DEC, HP, IBM, SGI, Sun • PCs

  7. Another Change:25 years of Tim’s Web My claim to fame: I refused an offer to become Tim’s manager! Before After 2014 2010 2006 2002 1998 1994 1990 1986 1982 1974 1978 1989: The Web was born The Web (as of 1989)

  8. Four Decades of Change inside a 50+ Year “Law” 2014 2010 2006 2002 1998 1994 1990 1986 1982 1974 1978 1965 2020? CHEP’95 IBM PC Moore’s Law • Moore, G.E.: Cramming more components onto integrated circuits. Electronics, 38(8), April 1965.

  9. The Future ? IoT (the Internet of Things) • Apparently, somebody (David Patterson?) said: • The first fifty years of computing were interesting, but wait for the next fifty! • One area that seems interesting (alongside BIG Computer Facilities):
