Reference excerpt

Rachel Marie Holden (also Armstrong and Hyde) is a fictional character from the Australian Channel Seven soap opera Home and Away, played by Amy Mathews. Rachel debuted on-screen during the episode airing on 16 January 2006. In 2010 Mathews quit the serial to pursue other projects and her on-screen husband Tony Holden was also written out. Rachel has been described as "work driven and professional" and a "sharp mind". Her storylines include a failed marriage to Kim Hyde, her marriage to Tony and suffering post-natal depression. Rachel went on a downward spiral following the death of her mother and a helicopter crash which she blamed herself for. Rachel committed crimes such as assault, drink driving and taking pills and alcohol. Rachel has also been kidnapped a total of four times throughout her duration.

Casting Mathews joined Home and Away in 2006, Rachel was introduced as an old friend of Leah Patterson-Baker (Ada Nicodemou). In 2010 Mathews quit the serial to pursue other projects and it was revealed that producers had decided to write out Jon Sivewright who plays on-screen husband Tony Holden. Commenting on their exits a spokesperson for the serial stated: "Amy Mathews is definitely going in a few months' time. Then, with Amy's character Rachel out of the picture, it was decided Tony should go with her, so Jon Sivewright is leaving too." Fellow cast member Rebecca Breeds who plays Ruby Buckton in the serial spoke out about their departures stating: "In terms of character, to see Tony and Rachel go is kind of upsetting because they fill a really important demographic – that middle-aged, new family thing and there's nothing like that on the show now so they're a loss."

Character development

Characterisation The serial's official website describe Rachel stating: "She has great instincts for people and has a sharp mind; she’s fiercely independent and has great strength of character." Of Rachel's persona, Mathews states: "Rachel is outgoing and fun with a sharp mind and good instincts for people. She has incredible strength and is fiercely independent. She has strong values and definite ideas about right and wrong but she is also a romantic at heart." Mathews has stated the likeness of herself and Rachel stating: "I wish I was more like my character- she's so together! As far as personality goes, she's really driven, and she's professional. [...] Rachel's a really bad cook, and I'm a good cook."

Storyline development In her later years Rachel embarked on an unexpected relationship with Tony, of this Mathews states: "It's a surprise love interest, someone who is not Rachel's type which is great because I think we should all try expanding our narrow type registers, thankfully, Jon and I know each other quite well, so it's no big deal." Mathews also recalled Rachel's relationship with Kim Hyde (Chris Hemsworth) stating: "He was really great and we had a great time, it was terrific to have the longevity of the working relationship in a marriage with him. But I am looking forward to what happens with Tony or with someone else." Rachel becomes central to a main storyline in which a stalker begins attacking females working at the hospital. Rachel later discovers that Reverend John Hall (Paul Tassone) is responsible when he takes her hostage. Mathews said that Revered Hall grudge against people who he thinks have acted immoral. In Rachel's case Reverend Hall believes Rachel is a sinner because she had a miscarriage and wasn't married to the baby's father Lewis Rigg (Luke Carroll). Reverend Hall also thinks that Rachel should sacrifice her own life "in exchange for the baby's". Reverend Hall begins to convulse and Rachel is given a "lifeline". Rachel goes as far to call for help and in hospital he is diagnosed with a brain tumour. Rachel realises his condition has contributed to his behaviour. Mathews said Rachel is the only one who can understand Reverend Hall's behaviour, because she is a doctor. She true to Rachel's nature she even "goes as far to forgive him", but she is alone as the other locals persecute him and the church. A big storyline for Rachel was suffering post-natal depression following the birth of Harry. While Rachel is pregnant and does not take any maternity leave. One of her patients Jane Avent (Felicity Price) loses her baby while Rachel is on duty and subsequently files a lawsuit against Rachel. When Rachel gave birth to a son named Harry, Mathews told TV Week that Rachel would begin to behave differently. Rachel feels "completely overwhelmed" and it was something she could not prepare for. While Tony is okay as he previously had children. However Jane begins to harass Rachel, Mathews said that Jane does not think it is fair that Rachel gets to keep her baby. She also stated that everyone is unsure that Rachel should have remained in work while heavily pregnant. As the storyline progresses, Rachel becomes more "possessive and controlling" over Harry and "abuses" Tony for not keeping her informed about him. Rachel shows a "side" of herself that no one has ever seen before. The lawsuit makes Rachel's anxiety worse and Mathews opined that Rachel and Tony's relationship turned bad because "they couldn't be further apart" while she goes through post-natal depression. Mathews stated "For Rachel to be cranky and sad for so long was really hard. I felt bad for Rachel and for the viewers constantly seeing me wailing!"

Worked examples

Example 1 — a first encounter with Rachel Armstrong

Start with the simplest possible case. Write down what Rachel Armstrong claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rachel Armstrong before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rachel Armstrong ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rachel Armstrong

In research: Rachel Armstrong appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rachel Armstrong in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rachel Armstrong is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australian female characters in soap operas, Fictional female medical doctors, Fictional medical doctors in soap operas, so understanding it makes those chapters shorter.
In everyday life: Look for Rachel Armstrong outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
