Klein paradox
noun
(quantum
mechanics)
A
surprising
result
of
applying
the
Dirac
equation
to
the
problem
of
electron
scattering
from
a
potential
barrier.
In
non-relativistic
quantum
mechanics,
electron
tunnelling
into
a
barrier
is
observed,
with
exponential
damping.
However,
if
the
potential
is
of
the
order
of
the
electron
mass,
V∼mc²,
the
barrier
is
nearly
transparent;
moreover,
as
the
potential
approaches
infinity,
the
reflection
diminishes
and
the
electron
is
always
transmitted.
Bhartrhari's paradox

Tullock paradox
name
liar paradox
noun
necktie paradox
name
Siegel's paradox
name
(economics)
The
phenomenon
that
uncertainty
about
future
prices
can
theoretically
push
rational
consumers
to
temporarily
trade
away
their
preferred
consumption
goods
(or
currency)
for
non-preferred
goods
(or
currency),
as
part
of
a
plan
to
trade
back
to
the
preferred
consumption
goods
after
prices
become
clearer.
