My Swedish Lesson for Today



My Translation: (Please comment if you actually speak Swedish and know how to translate it better. I am trying to learn.)
Do not be afraid.
I walk beside you.
Come take my hand.
I hold you near in my arms.
Can you dare to believe.
Lower your walls.
I will give you peace.

Because I love you just as you are.
Oh, I want to give you everything I have.
Oh, let me hold you when you are weak.
For you mean everything to me.

Do not be afraid.
I walk beside you.

Now I am yours
And now I can breathe.
Here I remain.
For here will I shall stay.
Look at us now.
Life is ours.
Do you see the future that we,
That we will make.

 Because I love you just as you are,
and I want to give you everything I have.
Oh, let me hold you when you are weak
 for you mean everything to me.

Yes, I will love you just as you are.
Oh, How I want to give you everything I have.
 Let me carry you when hope fails.
You mean everything to me.
Do not be afraid.
I stand beside you for you mean even more to me.

Graphene p–n and p–n–p Junction Devices

The observation of massless Dirac fermions in monolayer graphene has generated a new area of science and technology seeking to harness charge carriers that behave relativistically within solid-state materials1. Both massless and massive Dirac fermions have been studied and proposed in a growing class of Dirac materials that includes bilayer graphene, surface states of topological insulators and iron-based high-temperature superconductors. Because the accessibility of this physics is predicated on the synthesis of new materials, the quest for Dirac quasi-particles has expanded to artificial systems such as lattices comprising ultracold atoms2, 3, 4. Here we report the emergence of Dirac fermions in a fully tunable condensed-matter system—molecular graphene—assembled by atomic manipulation of carbon monoxide molecules over a conventional two-dimensional electron system at a copper surface5. Using low-temperature scanning tunnelling microscopy and spectroscopy, we embed the symmetries underlying the two-dimensional Dirac equation into electron lattices, and then visualize and shape the resulting ground states. These experiments show the existence within the system of linearly dispersing, massless quasi-particles accompanied by a density of states characteristic of graphene. We then tune the quantum tunnelling between lattice sites locally to adjust the phase accrual of propagating electrons. Spatial texturing of lattice distortions produces atomically sharp p–n and p–n–p junction devices with two-dimensional control of Dirac fermion density and the power to endow Dirac particles with mass6, 7, 8. Moreover, we apply scalar and vector potentials locally and globally to engender topologically distinct ground states and, ultimately, embedded gauge fields9, 10, 11, 12, wherein Dirac electrons react to ‘pseudo’ electric and magnetic fields present in their reference frame but absent from the laboratory frame. We demonstrate that Landau levels created by these gauge fields can be taken to the relativistic magnetic quantum limit, which has so far been inaccessible in natural graphene. Molecular graphene provides a versatile means of synthesizing exotic topological electronic phases in condensed matter using tailored nanostructures.

Ära Till Ditt Namn


I wish they would sing this song again at surfers church.


techno version:

Ära till Ditt namn
Matt Redman
Originalets titel: Blessed be the name
Svensk text Robert Eriksson
© 2002 Thankyou Music/ Copycare Scandinavia AB

Ära till Ditt namn
Då Du ger av ditt överflöd
Då Din frid kommer över mig
Ära till Ditt namn.
Ära till Ditt namn

På de vägar jag ej förstår
Genom öken och ödemark
Ära till Ditt namn
All välsignelse Du ger mig
Tackar jag Dig för
Och när mörkret sakta faller
Min röst Du hör

Ära till Ditt namn Du min Gud
Ära till Ditt namn
Ära till Ditt namn Du min Gud
Ära till Ditt heliga namn
Ära till Ditt namn

Då solens strålar värmer mig
Då livets glädje fyller mig
Ära till Ditt namn
Ära till Ditt namn

På en väg märkt av lidande
I försakelsens dunkla natt
Ära till Ditt namn
Du ger och tar igen
Du ger och tar igen
Mitt hjärta sjunger ut
Ära till Ditt namn

Is North korea performing Nuclear Weapons Tests for Iran?

Telltale Isotopes Hint at North Korea Weapons Test Science 10 February 2012: 643.DOI:10.1126/science.335.6069.643-a





The paper, Radionuclide Evidence for Low-Yield Nuclear Testing in North Korea in April/May 2010, is authored by Lars-Erik De Geer, Research Director at the Swedish Defence Research Agency, Stockholm.



This book is very interesting to me at least:

Innovation Hubs

Can you imagine two groups in the government ever cooperating with each other, much less working together? This video says some will be. This is the most positive sign I have seen that the government might improve.

Video Games versus Training Systems

The government has spent a fortune developing training systems.  Users however prefer video games and often do not use the training systems.  This is the only video I have seen that points out the difference between the two. Video games provide an entertainment environment and not a realistic or instructive training environment. The is another difference in that many training systems are intended to be integrated with real systems. It is fantastic that NASA supports education in this way.

$89.00 a year to view NASA's Section L2 website. Is that fair?

IEEE Global Humanitarian Technology Conference Theme Song
"Change the World"

Melody, lyrics: Helene Fung
Arrangement, Instrumentation: Malcolm Mah
Recording, Mixing: Malcolm Mah
Vocals: Helene Fung, Keegan Monteiro

We were born connected to the land
Through the land, we're all connected to each other
Hand in hand, we can make this world a better place
Improving people's lives
Our lives have been changed by technology
Tomorrow, the future will be brighter
Hand in hand, so many people will benefit
A new day has dawned for us
We have a duty (Put our minds together)
To help each other (We can travel all the way)
Through technology (and with liberty),
we can solve problems
We have a duty (Let our hearts beat as one)
Since we're born to care for each other
Together, we can change the world
Together, we can change the world
