These are a few of the ideas pupils are working on for their artwork on social change. They have now spent 2 classes in the library resource centre looking into the issues they feel strongly about and want to change to make the world a better place. The next step is to get on with their final design and create it!-good luck guys & keep up the enthusiasm

Breaking Bad : Season 2 : Episode 13 : “ABQ”

Walt pulls Jesse out of his retreat.

The season ends with both Walt’s and Jesse’s hopes for the future falling down around their ears, like aeroplanes out of the sky. Events have conspired to keep Walt out of the lab and classroom, so this episode contains nothing of note. Check back soon!

I’m not sure why Michael Slovis wasn’t assigned iodine (I), carbon (C), hydrogen (H), sulfur (S), oxygen (O) or vanadium (V).

Breaking Bad : Season 2 : Episode 12: “Phoenix”

Walt shows off the college fund.

As the season nears a close, it looks like Walt and Jesse are going to divide the profits and part ways. Events have conspired to (mostly) keep Walt out of the lab and classroom, so this episode contains nothing of note. Check back soon!

Breaking Bad : Season 2 : Episode 11: “Mandala”

Walt waits for the deal to end all deals.

Walt and Jesse decide to get out of the distribution business and focus on production, which is significantly safer. Events have conspired to (mostly) keep Walt out of the lab and classroom, so this episode contains nothing of note. Check back soon!

Fringe: Season 2: Episode 8: “August”

The restaurant runs out of chili peppers.

There’s more than one of everything – even Observers! This episode was refreshingly easy to watch.

This episode is debunked at Popular Mechanics and Polite Dissent, and you can read more about it at Fox, IMDb and the A.V. Club.

Random thoughts

That would have to be one of the most expensive security cameras in the world to be able to show the flight of a bullet. We can have a think about what would actually be required with a back-of-the-envelope calculation:

At the slower end, a handgun bullet might travel at 300 m s^-1 (just under the speed of sound), and the horizontal distance covered by the camera when Astrid was clicking through video frames was about a metre (based on the size of August’s arm). The bullet travelled about 60 % of the distance, or 0.6 m, in three frames and so we can conclude that each frame lasted for about 0.00067 s, which is 1500 frames per second. By way of comparison, video cameras generally capture around 30 fps.

Once again we can see some old-school communication equipment; this time a dot matrix printer. I posit (Walterism) that communication between the two worlds is only possible with equipment that existed before the event that caused them to diverge. It therefore looks like the two timelines separated in the 1980s, right when Walter was retrieving Peter.

This is bordering on the obsessive, but if Flight 821 went down two hours out of Rome then it could not have been off the Italian coast and was probably not in the Atlantic Ocean. Either it was two hours away and in the Atlantic Ocean off the coast of Spain or Portugal (or possibly France), or it was in the Mediterranean Sea (or even the Tyrrhenian Sea – technically these are within the Atlantic Ocean, but they are always referred to by their localised names) and closer than two hours to Rome.

The photographs and paintings of The Observer at key points in history reminded me a little of James in 12 Monkeys (he’s shown in a WWI trench). Perhaps it’s also how J. Robert Oppenheimer got the idea for his hat.

As is fairly common knowledge, screw-on silencers (or, more correctly, suppressors) do not “silence” bullets very much at all.

The Lewis Code

We are treated to another chemistry-inspired code this week, this time to do with the Lewis structure of atoms. However, like the code in Earthling it’s pretty much impossible to decipher.

Different atoms have different numbers of electrons, and this is one of the ways we can tell different atoms apart (it’s called the atomic number). However, the Lewis bonding model is all about electrons in the outer shell of an atom (the valence electrons), which are not so unique. Each atom in a group (a vertical column in the periodic table) has the same number of valence electrons as the other atoms in the group – this is one of the reasons why those atoms have similar properties. This means that for every dot diagram that Walter noted, there would be at least four elements that it could match (and possibly six, depending on the group in question).

Walter's Lewis structure code.

Firstly, Astrid’s code-cracking program would have picked up on some of the repeated symbols – for example, “7″, “As” and “N” are the same. Secondly, the numbers in the address do not seem to correspond to the number of electrons. It seems to be (number of electrons)+2 except in the case of “2″, though how Walter would know this is beyond me (perhaps there isn’t a 2536 Hastings). Thirdly, as I mentioned above, each symbol can represent different atoms (this is illustrated in the code with “As”/”N” and “Ti”/”Ge”). Walter would have found the address with a lot of trial and error, and could easily have gone to the wrong place – for example, by taking other elements in the same groups, we could make vaguely plausible names like “Kassipsis” (K-As-Si-P-Si-S).

A less ambiguous code?

On top of all that, titanium (Ti) is a transition metal and has partially filled d-orbitals. We do not normally describe transition elements using Lewis structures, as they tend to break the rules – this is one of the reasons why the Lewis model is not used very much in modern chemistry. Titanium does have four valence electrons, but it would be unlikely to come to mind from a Lewis four-electron diagram (though perhaps Walter thinks in unconventional ways).

In order to make the code clearer, there would have to be some method of either identifying the correct period (row), or identifying the number of electron sub-shells underneath the valence shell (though of course this would also make it easier for someone else to decipher). I propose a second symbol (inside the large circle) to identify the electron shell that is being filled, and more dots to identify the correct period. Thus an empty circle would be interpreted as a number, a second circle (s-orbital) as groups I and II, a looped cross (d-orbital) as groups III-XII and a figure of eight (p-orbital) as groups XIII-XVII. The code would then look like the second diagram on the left – more complex but unambiguous.

My kids are some of the most thoughtful kids I know.  I know you probably think I am biased, but they really are extremely aware and respectful of other peoples’ feelings.  Even with each other, although they are close in age and with each other all the time, they practice compassion and thoughtfulness.  I’m not bragging or claiming this as an awesome parenting victory.  This one is all God.  Superman and I try to model and demonstrate such love, but we aren’t perfect.  You see, when I was “surprised” by my pregnancy with S2, just four months after S1 had arrived, I prayed, HARD!  I prayed for their development and their ability to get along.  God delivered, and He’s offered that same gift to us with each child.  I am grateful.  I’m not one of those parents bent on my children reaching (or racing to) certain milestones.  They’ll get there in their time, and when they need extra help doing so, we make sure they get it.  This, however, is a goal that melts my heart.  My 3 yr old son, who is every bit a rambunctious and wild little boy, came looking in the bathroom for his brother to give him his backpack today.  You don’t understand, either.  This isn’t just some backpack.  For a few months, S5 slept in this backpack.  It is very special to him, and S4 wanted to make sure that he gave it to him this morning.  As I type this now, I’m hearing S4 say to S5, “You wanna try that?” and S5 replying, “Yeah, sure, I wanna try that.  Do you wanna try that?” in his squeaky 2 yr old voice.  All the while, they are including their 1 yr old brother in their fun.  Little boys.  I don’t know if you realize this or not, but little boys don’t act that way a whole lot.  You might at one little boy who is sweet as can be, but put him with another little boy, just one year older or younger, to live and breathe with every day, and it can get tense!  That’s the one area my mom, who is my mommy mentor, has not mastered.  She was a wonderul mother and almost always has the answers to my parenting questions, but she only had one boy.  It’s different.  Just trust me when I say that.  So for Thoughtful Thursday, I’m going to abandon my post and finish listening to my boys being thoughtful of one another.  In a matter of seconds, it could be a totally different story!!!

Breaking Bad : Season 2 : Episode 10: “Over”

Walt investigates the water heater.

With a little down-time, Walt embarks on some home improvement and Worst Role Model projects. In this post, I’ll be talking about safety matches.

You can read more about this episode at AMC, IMDb and the A.V. Club.

Random thoughts

When Walt is extolling the virtues of the new water heater to Walt Jr, he says that it’s “117,000 BTUs.” The British thermal unit is an older unit of energy that has now been effectively replaced by the joule.

When Walt was walking away from the would-be-meth-cooker’s abandoned equipment, I was certain that he’d mutter “amateur” under his breath.

Phosphorous in matches

Our uninformed cooks are buying matches for a source of red phosphorous, which is required in the red, white and blue process to convert (pseudo)ephedrine to methamphetamine. Walt points out that they need the striker strips rather than the match heads – “strike-anywhere” matches do contain phosphorous, but the safety matches that are more or less ubiquitous these days do not. The dangerous components are segregated into the strips and heads, which means that matches cannot ignite by accident (e.g. on cowboy stubble).

Matches are (intentionally) ignited through friction – dragging the head against a rough surface generates enough heat to convert some red phosphorous (in the striker strip) into highly reactive white phosphorous, which then ignites upon contact with the air. This additional heat is enough to decompose an oxidising agent in the match head (usually potassium chlorate), releasing oxygen. The oxygen-rich atmosphere around the match head plus the heat from the white phosphorous are enough to ignite the main component (sulfur), which burns for long enough to set the wooden matchstick alight. The characteristic smell of a burning match is caused by sulfur dioxide, with perhaps a dash of carbon (soot) and phosphorous pentoxide.

I’m not sure why Michael Slovis wasn’t assigned iodine (I), carbon (C), hydrogen (H), sulfur (S), oxygen (O) or vanadium (V).

Fringe: Season 2: Episode 7: “Of Human Action”

Olivia and Walter in the aftermath of a typical action.

Amazingly, an experiment at Massive Dynamic had some unforeseen (?) consequences and a psychopathic teenager with the ability control minds is let loose. The usual impossibilities aside, there isn’t very much physical science here so this episode contains nothing of note. Check back soon!

I just created three pages to the right – Graflex Optar page 3 / VPK Meniscus Images 003 / B&L Rapid Rectilinear

Our trip to the Statue of Liberty, for several small reasons, all added up to a cancellation. Perhaps next Spring.

I am rapidly learning to enjoy the Olympus E-510 and its ability to work with my old lens collection. The Fuji S2Pro needs the Nikon AF lens line, it doesn’t work well MF. The Pentax *istD has a nice feel to it, but I have yet to warm up to it. The Canon XTi, due to the wide range of good glass available to me, is the first to be grabbed for general shooting.

Am letzten Wochenende lief der dritte Spieltag auf Landes- und Bezirksebene ab und nur unsere zweite Mannschaft konnte durch einen Auswärtssieg und einer knappen Niederlage überzeugen. Hof 3 und 4 verloren mitunter deutlich…

Den Mannen von Hof 2 (Hans B., Micha und Magnus) gelang es in München, den Münchner SC 3 mit einem 5-1 in die Schranken zu weisen. Im zweiten Spiel gegen den SC Kempten 1 verlor man allerdings knapp mit 2-4. Dabei sah es lange Zeit gut für die Zweite aus, doch am Ende konnte sich Kempten laut Micha`s Aussagen mit teilweise “komischem Spiel” durchsetzen.
Dennoch wurden zwei Punkte aus München mitgenommen und so verweilt man nun auf dem sechsten Platz.
Ligatabelle Landesliga Bayern

Die Jungs aus der Dritten (Hans S., Dirk und Thomas) hatten eigentlich vor, aus dem Keller der Bezirksliga herauszukommen, doch schafften sie es leider nicht. Man verlor zuhause mit 2-4 gegen den CSC Regensburg 2. Eigentlich lag man schon mit 0-4 hinten, aber am Ende konnte man doch noch zwei Spiele durch Siege retten und verhinderte somit die “Klatsche” auf eigenem Terrain. Positiv zu beobachten war Hans Saupe, der seine beiden Gegner mit starken Safetys und abermals typischer Ausdauer nervlich “auseinandernahm”.
Trotz alledem wird es nicht leicht, die Klasse zu halten. Bis Rang 3 fehlen zwar nur zwei Punkte, aber allein für die Moral der Mannschaft muss am nächsten Spieltag ein Sieg her.
Ligatabelle Bezirksliga S2-A Bayern

Und auch unsere bisher “hochgelobte” vierte Mannschaft (Thilo, Flo und Jörg) musste im heimischen “Stadion” eine herbe Niederlage hinnehmen. Gegen die Pool Factory spielte man 1-5 und hatte damit die ersten Niederlage in der noch frischen Saison in der Tasche. Sehenswert waren 35 Punkte in Serie von Thilo aus dem ersten Spiel.
Die Mission Wiederaufstieg ist zwar immer noch machbar, aber es wird nun sicherlich ein etwas beschwerlicherer Weg werden.
Ligatabelle Bezirksliga S2-B Bayern

Last but not Least kam gestern unsere Pokalmannschaft in Selb gegen den BC Selb 2 zum Einsatz und gewann deutlich mit 4-1. Thilo war an diesem Tag wohl ein wenig gerädert, denn anders als in der ersten Runde des Pokals kam er überhaupt nicht sein Spiel. Flo dagegen spielte einen seiner beiden Gegner mit einem 32-er Break an die Wand und sicherte sich damit das höchste Turnierbreak in seiner bisherigen Snookerlaufbahn. Glückwunsch!
Olli spielte sein Spiel mit mehreren kleineren zweistelligen Breaks herunter und gewann seine Partien. Damit rückt man dem “Projekt Elchingen 1″ ein Stück näher, denn nun ist man schon unter den letzten 16 verbliebenen Mannschaften.

Wie wird es wohl weitergehen? Man darf gespannt sein…

I love the look of the sample pictures that Dpreview.com published recently for the Leica S2 medium format camera. They warn that they are not from a production camera, but I don’t think Leica would have let them publish pictures unless they felt they are representative.

See http://www.dpreview.com/gallery/leicas2_samples/

I like the understated British way Dpreview describes them as “snapshots”. If Dpreview was an American site the description would be littered with superlatives and exclamation marks!

I particularly liked the two black and white pictures at the end taken by Dpreview’s founder Phil Askey. He does not seem to write camera reviews any more but I am glad he is out and about photographing.

GUIDA PRATICA ALLA SCELTA DI UNA SCARPA ANTINFORTUNISTICA

SOMMARIO DELLA GUIDA :

PRIMA PARTE :  CONOSCERE LE CERTIFICAZIONI (dopo l’introduzione)

SECONDA PARTE : LE PARTI DI UNA SCARPA DI SICUREZZA

TERZA PARTE :  SCEGLIERE LA SCARPA DA UOMO

QUARTA PARTE :  SCEGLIERE LA SCARPA DA DONNA

INTRODUZIONE :

Dopo aver recensito decine e decine di scarpe antinfortunistiche, abbiamo pensato che tutta questa scelta può creare confusione o difficoltà nei nostri clienti. Il mercato in effetti offre tantissime alternative e, spesso, è facile sbagliare acquisto senza conoscere le caratteristiche tecniche e di sicurezza della scarpa che si stà acquistando.

Da qui, l’idea di questo articolo. Composto da quattro capitoli  sempre in aggiornamento dove riverseremo tutte le informazioni e i consigli per scegliere la scarpa da lavoro ideale

Inizieremo spiegando il significato delle certificazioni delle scarpe,  elemento fondamentale per conoscerle appieno. Quindi elencheremo ogni parte che compone la scarpa, come fosse l’analisi di un’automobile e spiegheremo tutti i materiali e le tecnologie applicate. Infine negli ultimi due blocchi entreremo nell’aspetto pratico e vi guideremo nella scelta della scarpa ideale per i vostri piedi, per uomo e per donna.

Da quando la sicurezza è legge nelle aziende, è aumentato il numero di settori che deve utilizzare le scarpe antinfortunistiche. In passato solo chi lavorava in cantiere ne faceva uso, ma oggi persino in bar ed alberghi c’è l’obbligo di indossarle.

CONOSCERE LE CERTIFICAZIONI

La certificazione minima richiesta è SB (S=Sicurezza, B=Base). Questa sigla attesta che la scarpa soddisfa i requisiti fondamentali della norma EN345 che richiede il PUNTALE D’ACCIAIO da 200 Joule.

Aggiungendo una suola antistatica con assorbimento di energia nella zona del tallone e sua relativa protezione, la scarpa sarà certificata S1.

Una scarpa S1 in pratica ha una protezione con puntale d’acciaio per le dita del piede ed una suola antistatica ma sprovvista di lamina antiperforazione.
In genere le scarpe S1 sono utilizzate da magazzinieri, operatori alberghieri, industria alimentare e tutti quei mestieri che non hanno rischi per la pianta del piede (tipici dei cantieri con chiodi a vista).

Restando su scarpe senza protezione alla pianta del piede, la certificazione S2, descrive una scarpa S1 dotata di tomaia in pelle o qualsiasi materiale impermeabile per un tempo maggiore di 60 minuti. Queste scarpe sono adatte per chi lavora a contatto con liquidi che verrebbero inevitabilmente assorbiti da scarpe S1 con pelli scamosciate. Solitamente le scarpe S2 hanno pelli in nabuk, fiore o anche scamosciate ma con un trattamento idrorepellente che le renda ugualmente impermeabili.

Elevando il livello di sicurezza, troviamo le classicissime scarpe S1P ed S3 che non sono altro delle scarpe S1 ed S2 dotate di lamina antiperforazione. Quest’ultima può essere realizzata in ACCIAIO o in KEVLAR (la cosidetta lamina in composito ovvero NON-METALLICA).

La certificazione S4 ed S5 determina scarpe impermeabili al 100% come stivali in gomma o scarpe con inserti in materiali sintetici che sono water resistant in qualsiasi condizione. La scarpa S5 ha in aggiunta la lamina antiperforazione, che troviamo negli stivali di sicurezza nei cantieri e nelle scarpe alte come la famosa STOP RAIN.

Il nostro articolo prosegue nella seconda parte dove esporremo tutte le tipologie di scarpe di sicurezza e le loro caratteristiche.

Baby, you may not know but I do. I do, I do. I do love you.

It sounds weird for sure and you may not love me no more.

This is, if you’ve ever loved me, what I doubt.

But believe me when I say: ” My love will survive when nothing else is alive. It’s forever and ever, it’s yours even if you don’t want it. I’m sorry but I just can’t deny it, I can’t hide it anymore. I believe you should know, because who loves another is not supposed to lie about it. “

You can run from me, you can blame it on me, you can tell your friends, you can point and laugh at me. But please don’t do this, or I’ll have to punch your face.

Anyway baby, if you don’t trust me, just look into my eyes. Do I seem to be kiding you? No? That’s what I imagined.

And if you still have any doubts check out the way I stare. It’s fair, if I’cause even when I can’t have you, I can still see you.

I’m sorry, babe, but I just can’t take my eyes off of you.

Winola Weiss.

S3 and S2 pupils have just started to create posters where they decide on a topic in society that is important to them personally and create a poster that will educate, inform and hopefully improve the world! This links in with a forth coming exhibition on Art for Social Change at the School of Visual Arts Museum in New York City. We have only spent one period discussing our ideas and looking at some contemporary poster designs, but already I am impressed with the pupils enthusiasm.  The boys in particular were great and I thank them for all their thoughts that they brought into the discussions- come on girls get your thoughts out there as well! We only had time after I went on and on for too long (sorry) to just quickly brainstorm some topics and then start a mind map. I have now asked everyone to leave a comment with their idea for a topic and a quick description for how it could look in poster format on this blog. I’ve booked the library next week so they can all do some more research and be better informed themselves. For those of you who don’t have a clue what to do yet- have a look at the comments they might help you to get some ideas going! Any questions? ask and I will reply

Fringe: Season 2: Episode 6: “Earthling”

The cosmonaut's final journey.

Monsters! From outer space! And Cold War references! Typically poor alien logic aside, this episode was refreshingly easy to watch.

This episode is debunked at Popular Mechanics and Polite Dissent, and you can read more about it at Fox, IMDb and the A.V. Club.

Random thoughts

The “dust” that our victims are turned into appears to be vacuum cleaner lint, which may be why Walter requested a Dust Devil. If a body had indeed been reduced to its “elemental components”, it would be much smaller as the gases (most of the human body being hydrogen and oxygen) would have dispersed.

Once again, the slightest shock will incapacitate women – even professional nurses – by causing uncontrollable screaming.

If the space shadow needed to feed on radiation, it seems odd that it’d go around killing people when it could just go hang out inside an X-ray machine or PET scanner.

The chemical code

At first glance, the formula puzzle that Tomas sent to Broyles all those years ago appears to be some kind of porphyrin. Porphyrins are quite common in nature and biochemistry, one of the better known derivatives being haem B (found in blood). Peter was right in recognising it as a “complex organic compound”, though it’s more strictly an organometallic and the term “molecular model” is generally reserved for 3D representations (either physical or computer-generated).

The puzzle molecule and porphine, a simple porphyrin.

Of course, we don’t know what all the Russian notes and Greek letters mean – though we may speculate that Tomas’s γ key doesn’t work given the use of α, β, “C” and δ to label the pyrrole rings. Also, the molecular diagram as shown in the episode has double bonds between every atom in the α ring – this structure cannot exist, and so I’ve left it out of the diagram above. The Φ should represent a metal of some kind – in haem, this is iron (Fe).

The groups linking the pyrrole rings together are less easy to interpret, as four of them (CHα-, CHHHβ, HHα and HHδH) cannot exist. CHα- and CHHHβ have carbon exceeding its maximum valency (i.e. the atoms have more than four bonds), and HHα and HHδH make no sense (I suspect that HHδH is a typo, and that it should be CHδH – though this still cannot exist). Similarly, the CO₂H groups – normally representing carboxylic acids – cannot exist as drawn.

Moving on to the functional groups, the “M” in CMα and CMδ can be used to represent a metal. However, direct carbon-metal bonds usually form only under very specific conditions and are highly unstable. M may therefore be a reference to another molecule, such as another organometallic.

Finally, the [αβ], [αα], [ββ] and [βα] again make little sense without further information. We can, however, see the Roman numerals I, II, III and IV, which Walter seems to think represent four nucleobase-like molecules. They aren’t the bases that make up human DNA, but they have very similar shapes and so might be considered nucleic acid analogues (and therefore space creature DNA). Later on, Walter starts drawing what look like polysaccharides – large polymeric molecules used for storing energy in living systems.

Walter also mentions titanium tetrachloride (TiCl₄), which is not shown directly in the diagram. Instead, we see a dimeric form of titanium trichloride (Ti₂Cl₆ = 2 x TiCl₃), which can react at high temperature to form TiCl₂ and TiCl₄.

The gigantic molecular model that Walter and Peter build towards the end of their research looks like a small protein, or possibly a Theo Jansen piece. Presumably the linking bond means that human and alien parts are irreversibly entwined – but this should also have been clear from the 2D diagrams.
