along with the temperature
records have fallen across the united
states thanks to a winter storm that's
scraping across the country
I'm Carl Azuz thank you for taking 10
for CNN
of the 48 states in the contiguous u.s
the government reported that snow was on
the ground
in 45 of them that happened on tuesday
morningonly florida georgia and south carolina
were snow free at that time
the snow covered more than 73 percent of
the country outside of alaska and hawaii
that's the most coverage the nation has
seen since records of this
started being kept in 2003 it's fun for
folks to play in
it's not fun if they have nowhere warm
to go afterward
that's a big enough problem to cause
states of emergency in places like west
virginia
kentucky and texas more than 10 inches
of snowfall has piled up in the central
part of the lone star state
below freezing temperatures were
recorded in every part of the state
that's put a record amount of demand on
the state's electrical grid
and then the power went out several
million texans couldn't turn on the heat
yesterday
some retreated to shelters or ran their
cars outside on streets and driveways to
get warmenergy officials say limited natural gas
supplies are part of the problem
so are frozen wind turbines they
generate an estimated 25 percent of the
state's power
but the ice storm caused some of them to
shut down or freeze up
freezing temperatures and power outages
are pummeling areas from texas
through the plains states more than a
third of the country
reached temperatures below zero on
monday texas is receiving the brunt of
the stormwith millions across the state left with
no powerand no heat we all see the current
situation i'm not going to sugarcoat it
the next few days are going to be very
tough there's a high chance the power
will be
out first for these folks until the
weather gets better
which will not be for a couple of days
the city of abilene that has a
population of more than one hundred
thousand residents
was forced to shut off water last night
due to power outages
the lacking infrastructure for these
conditions is a major concern for hard
hit areas
with some families freezing in their
homes it's like a walk-in freezer
it's like 34 to 36 degrees i would say
it depends on which room you're in 40
degrees is at the lowest end to
55 at the highest in harris county power
outages nearly spoiled more than 8
thousand coronavirus vaccine doses
moderna advised the county that 3 000 of
those doses
could go back into storage and the rest
were distributed throughout the county
historic lows in dallas oklahoma city
and in kansas city
the coldest since 1989 the wind chill
factor reaching temperatures
as cold as minus 32 degrees
in tennessee authorities reported two
fatalities from the storm on monday
in kentucky the governor is warning that
another storm is on its way
he tells residents not to run your gas
ovens to generate heat
and be careful using generators and camp
stoves
again i can't stress the dangers of
carbon monoxide poisoning
which is absolutely avoidable
those are casualties we don't want to
see
we did not make it through almost a year
of a pandemic
to lose people to a snow or an ice storm
ten-second trivia which scientists work
gave rise to the theory of plate
tectonicscharles richter ingaleman alfred wegener
or ian malcolm
beckner's theory of continental drift
led to the theory of plate tectonics
wagner's book on continental drift was
published in 1915
it was not well received in the
scientific community
but over the decades as more discoveries
were made the theory of plate tectonics
gained acceptance in the 1960s
and that helped explain wegener's theory
of continental drift
research on this continues today this is
an animated computer model that shows
the movement of tectonic plates
the giant theoretical chunks that
compose the earth's outer crust
geologists are using this to examine how
plates might have interacted along their
boundaries
it's the first model of its kind and
researchers hope it'll help geologists
understand the history of our planet
meantime technology is trying to
understand the expressions of your face
an artificial intelligence tool is
gaining usage at a time when more people
are learning and working online
critics don't like the idea of laptop
cameras for instance
tracking users faces especially when it
comes to students
but applications for this could go well
beyond the online classroom
our faces say a lot about us whether
we're happy
angry or sad facial expressions are a
big part of how we communicate with each
other
but what about when we can't see each
other's faces
for teachers around the world it's
become a problem
including in hong kong when most of
katim chu's classes went online
he struggled to stay connected to his
students through the screen
when i'm standing in front of the
classroom i always
observe the reaction and then the face
the emotion of students we cannot
see face-to-face teaching at this moment
and we don't understand their progress
one solution is helping chew to read the
room
artificial intelligence that analyzes
students emotions
as they learn it comes from a local
startup
find solution ai
we develop motivation ai especially to
help kidsusing emotion detection to observe how
they learnand motivate them to learn in a better
way we can motivate them by giving some
easy questions
we will also give them some video chunks
to guide them
when they are not understanding
something new so it's like a teacher
sitting next to the kid but the teacher
is not there but it's the software
says the software works via your webcam
or camera
measuring the position of your eyes
eyebrows mouth and other features to
detect for six emotions
happiness sadness anger fear
disgust and surprise for example
if the corners of your mouth are raised
this would tell the ai that you are
happy
while a wrinkled nose would signal
disgust and the ai is pretty good at it
lamb says
for the accuracy for the emotion
detection we scored around 85
percent but can just six facial
expressions really convey a range of
feelingsaccording to experts the answer like
emotion
is complex
so there are what we call primary
emotions so you can tell somebody's
angry or sad or happy
from any culture pretty easily but there
are otherswhat we call secondary emotions that can
be harder and can be cultural dependent
and can be gender dependent we're not
able to recognize secondary emotions
with such high accuracy machines can
already do that
better than some human beings we would
like to train the machines to be
not just as good as humans that it
should be better than the average human
fine solution ai is one of a number of
developers racing to advance the
technology
already lam says the number of schools
using its learning platform has more
than doubled since the pandemic began
as users grow so do concerns around
privacy
in the classroom we need to gather
consent
right to be a part of this program to be
monitored
in terms of facial expressions more
importantly
we need to explain to them how we use
their data
lam says bind solutions ai software
doesn't store videos or photos
and parents or students can always
choose to turn off the camera
this feature could give the startup an
edge as global demand grows for machines
that can read our emotions
it's a business that's set to reach 56
billion dollars by 2024
with benefits not just for the virtual
classroom but also the virtual workplace
from employee well-being to online
meetings during the webinar or during
the video conferencing you want to know
if that person is engaging or they just
turn on the camera but that person is
not literally there
so that is reason why we also expecting
to move forward to other
industry face-to-face communication is
still a way off for many people
but a solution in the meantime could be
staring us right
in the face
so just how big a drawing can one person
do with a marker
that was the challenge for an art
teacher in philadelphia
and this is the work she drew it
apparently set a record for the largest
drawing ever made by an individual
its size 6 450 square feet
its features sky and sea with city
buildings in between
its total time to complete 63 hours
the work is made up of the kind of
doodles you might have done in class
just a wee bit bigger so i guess it was
a pretty sharpie idea to cray all over
the room
because in making her mark she met the
mark while marking up the floor in a
mark or break record
attempt that is pretty remarkable we'll
just have to see how permanent it is
shout out today goes out to rising sun
high school it is in the picturesque
sounding town of rising sun maryland
